Examples:
1. Rangers and bards now get 6 skill points per level. I believe that many characters that are now being built as Rogues will switch to either ranger (sneaky/hidey scout who is alert to danger) or Bard (charming diplomat that takes over character interaction).
The ranger will make a better scout because he will now have enough skill points for all of Spot, Listen, Move Silently, Hide, and Wilderness Lore. He has the track feat. He has the best BAB. Even now, the ranger is tempting for this role. With 3.5e, it looks like it may become the best character for this role.
On top of better HD and BAB, the ranger has spells.
The bard has almost the same skill list as the Rogue. In exchange for the sneak attack, evasion, and uncanny dodge he gets the song ability and spells. The main things he can't do skill wise are traps and read lips. For many of the character concepts where people were taking the diplomacy skills, the Bard now becomes the obvious winner.
2. Multiclass spellcasters. As shown by the Mystic Theurge, PrCs are now going to be the way that you're supposed to make a multiclass spellcaster worthwhile. There are other examples, such as the Spellsword and Arcane Trickster, but those were just as much about adding style and abilities related to that style as they were about game mechanics. The Mystic Theurge is all about mechanics.
3. Changes to spells. I can't help but think that many Sorcerers are going to want to change their spells known after the new books come out, as some spells (such as Haste) change the way they work and other spells change in spell level.
Looking over the material, I can't help but feel that the changes will have unexpected consequences on all characters and the way they are built.
I agree, in that new characters may see some new avenues and possibilities open to them with 3.5e. I disagree, however, that 3.5e will radically change current characters (straight rangers or bards and spell selection among sorcerors aside).
To point out my meaning with your examples:
1. Yes, I think that many character concepts that currently flock to rogue as their solution may find they would rather do ranger or bard as their central point. But many won't. You have the option of being a scouting ranger or a diplomatic bard or the corresponding rogue. You trade the spells (and BAB/combat paths of the ranger) for sneak attack and a few exclusive skills, in addition to being able to add 2 full-level skills MORE than the base concept in the corresponding non-rogue. You could be a scout ranger, or you could trade your ranger spells and a bit of BAB for sneak attack and, say, disarm traps and bluff, for example.
As for current characters 'changing' their rogue levels to ranger or bard, I just don't see it as a prevalent desire. Here you've got a character that's been played for a while, and has developed into the party's solution for situations
x,
y, and
z. He can do this because of his 8 skill points. Sure, he could change to be a ranger or bard, and still handle the party's
x and
y situations, but he'd be swapping
z for some other situation/ability
w. And while the player might want to play an
x,
y, and
w character someday, that isn't what
this character is.
2. Multiclass spellcasters have always been something that just didn't work well in 3e. Or have they, on a limited basis? Could one argue that the paladin, ranger, and bard are (or could be considered), on some level, multiclass cleric/fighters, druid/fighters, and wizard/rogues? The Mystic Theurge isn't, in my opinion, some harbinger of doom, it's just a stab at trying to make multiclassing spellcasters with another spellcaster feasible.
While I can't say that I think it doesn't look a bit, well, strong, I haven't seen it in action, and in any case I think it provides a good template from which you could model a customized PrC to fit your campaign and the multiclass your player wants. If you think it's fine as is, but want to multiclass two divine classes, just change the requirement from arcane/divine to divine/divine, modify the skill set, and see how it looks, maybe clarify how spontaneous healing works, and go with it. If you think it's too strong, up the ante on prereqs, thus lowering the eventual maximum caster levels.
As for whether people will want to change their 10th level mage to a MT, I think MT will merely just be tacked on to a player's "to play in the future" list, since the MT really looks like it needs to be the focus from the get-go of the character to be worthwhile.
3. Sorcerors and changes to spells are one area where I do think there will be some retroactive character adjustment going on. But I can't think of a way to prevent it, and it's not like it's a major change to the way the character will be modeled.
As always, YMMV, and I do expect some exceptions to my predictions about widespread character alterations.
