I'm surprised to read so few mentions of Pathfinder's
Ultimate Psionics. Everything I read suggests it's much better than 3/3.5 Psionics. I know
I like UP so far, but I'm not familiar with 3e psionics.
Whatever they do with psionics, I hope they throw a bone to those of us who want to rip out arcane & divine magic and replace both with psionics (and call the result "magic"

). E.g., psionic classes that replicate Wizard (with spell lists as broad) as well as Sorcerer, and maybe Bard, Ranger, and Paladin, too; psionics that are as broad in scope as arcane & divine magic taken as a whole.
The majority of nerdrage over 5e seems to be based in nerdLOVE over 5e (it is for me, anyway). As in, "this game is AWESOME! Why can't I buy MORE of it???" I assure you very few 4th edition detractors were out there converting 3rd edition products to play 4e, nor 3rd edition complainers grabbing 2e sourcebooks to convert and play 3e. It is definitely not something I've seen in the game's history since I've been playing.
Like I said in the crystal ball thread...it's just
damned odd. I don't have WotC's inside knowledge, obviously, but from here it looks like Hasbro's trying too hard to fight the last war.
I predict psions will use spell.
Psionics fans will be angry at first but they will get of it. No one is going to rewrite all the spells as powers/sciences/disciplines except for book fodder.
If they do this (and I'd be okay with that; it's what I'm in the process of doing myself), my first instinct is to say that's not enough for a hardcover, so they should release the player rules as a PDF, and make the hardcover a DM book, maybe an adventure path cum psionic setting.
EDIT: I think he hinted UA. BUT, in case we somehow need to be reminded, the other way it comes out is they do some DS related story, and this is the bonus material.
Yes, this would mesh well with what they've already done so far. A Dark Sun AP/Sandbox/Setting hardcover, plus a Dark Sun/Psionics Player Guide PDF on the website.
I disagree with Yaarel's insistence on what he describes in MIND-OVER-MATTER FLAVOR. I'd be fine with psionics that have a core of purely-character-powered spells (say, mostly the mental powers like telepathy and such), but also outlying spheres where the character uses mental powers to tap into other power sources. Summoning and conjuration in particular work better for me this way; the mentalist uses his telepathy to contact another plane, call beings there into his reality, that sort of thing. I also prefer the UP model, where Int is the prime stat.
Actually, now that I think about it, maybe limted-scope 5e psionics rules from Wizards would be best. Then we could turn to the 3rd party publishers for something really good, like UP.
I want to see a 1e version of psionics. That way, you won't have everyone and their grandma's dog wanting to play one, but only those hardcore players who REALLY want to deal with it.
Then again, I've never really liked the class in a D&D world. And no, I don't play Dark Sun. I know, I'm weird like that.
You're describing how I used to be about psionics, before 3e. Now I'm trying to figure out how to replace magic with psionics (and then call it magic, lol).
If you have magic why even bother with psionics? It seem redundant.
