I wasn't disappointed with the announcement, because I already knew Paizo wasn't going to do power points and that psychic magic was going to be vancian. That's been abundantly clear from following the Ask James Jacobs thread. Normally, he's doesn't talk about potential future projects, but he's been pretty adamant that psychic magic, when it was done, would be vancian and wouldn't involve power points.
Not really true Vancian. Spontaneous casters are not true Vancian.
Prepared Casters in PF are pretty darn close to true Vancian, just some of the flavor text about "forgetting" is gone, and of course unlimited cantrips, etc.
Having played with Spell points, I can't see how it's any advantage at all. It's easier to Nova, and easier to cheat (even if inadvertently). Other than that it's just Fantasy Accounting.
Vancian is the most popular and easiest to master FRP system. It's also very common in Fantasy literature, whereas I dont remember any books where the wizard or psion has 'points".
Yes, the meme where you use "energy" is common, but then that usually drains you or make you tired. Psionic Points or Spell points dont do that- or at least dont in any system I have played. In most systems, after using 99% of your "power" you are just as "strong" as a Fighter who is down 99% of his HP.
You can just as easily say the Spontaneous spell-slots are using "energy" as Spell points. It's just flavor.
