Sweet! Personally, I love WotC's d20 system, and I'm glad they're going to be using it.
I'm glad they're not using the standard psionic rules for telepaths, though. That's one area where I feel that the new system lacks. They've made it too much like their magic system and psionics don't really feel like anything special now. I understand the reasons for that, but I don't much like the end result.
I very much agree - the psionics in the 3rd Ed. moved to far from making psionics 'different' and mysterious. I'm curious to see what they've done with the system for the P-ratings. I might adapt it into my DnD champain.
