I think they're just plain not going to produce any more support for one leg of each V class. For example, all Cleric material from now on might be designed for Wisdom-primary Clerics, and all new material will either ignore or recommend against Strength-primary Clerics (in favour of Runepriests, perhaps); it's not that Strength Clerics will be totally hosed -- options already exist, and Strength may become a secondary stat -- it's just that this way, support can be focused on Clerics without having to split between two virtual-classes... because that's what the V classes are: two virtual-classes in one entry. (Think Rangers -- these guys could've been two different classes. Dexterity and Strength Rangers are worlds apart.)I agree that A shaped classes are simpler to build and in some ways offer the player more flexibility with a given character. I think they may well saw a leg off the V shaped classes, but I don't think they will REWORK them, just leave out options. So we may only see the Wis based cleric and the Cha based paladin, but I don't think they will REMAKE them into A shaped classes, I think they'll just offer one of the two existing options (or a 3rd option that is based on one leg only). So the Wis based cleric we'll see in Essentials will be essentially the same Wis based cleric we have now and the Str based cleric powers will simply be left out and replaced with some new Wis based ones or some from DP etc.
Paladins might get a build that tosses both DC and DS for a simpler or more coherent option say. It will be consistent with existing rules and use a lot of existing powers, it just won't be a specific build you could do with the PHBs.
QFT.Yes, it is. If the race can play more classes more effectively, it is more powerful race. If it can fit into more niches (and race+class in 4E is terribly niche-centered) then it is more powerful. This argument makes no sense except maybe in a white tower of academia sort of way.
This is one aspect of 4E I dislike (not that previous editions are at all better). Races are pigeon-holed, and have to compete with other, similar races for relevance in each niche, and some races succeed in more niches than others. Shardmind, Dwarf, I'm looking at you guys...
