Thanks OU812 for the great write up for a 4th ed. Psion rules.
Looking at what Wizards has coming out in 2009, unless PH2 surprises us, I doubt we'll see anything for Psions.
I've been running 3 year old Eberron campaign, which I switched over to 4th last year. It has been pretty easy to let the players remake their character as 4th, and I as the DM give a few extra powers to each translating 3.5 into 4th to keep continually. Only one player had trouble, the Half-elf Lyrandar psion sailor. We use the wizard as the base, but we sorta guess how what powers would translate. I guess we both were lazy really did want to write everything down as you did. Man this is great, I like what you did. We'll be using this weekend.
As inkpenavenger posted, crystal implements really fit. Crowns, Rods, Orbs, wands, staffs, stones, weapons would work. Tying an implement extra bonus to a specific psion power type might work. I don't mind the implements that are used by other classes needing a feat, but some just for the psion should be a part of the class.
As ranig posted, you might follow the same color coding for powers that the 4th books. As for roles, I like the concept your sorta general till paragon then that defines a 4th role, which opens into powers for each type of psion.
As Paultimatum posted, there are some good points. I play with what you have, and see what my players think.
Any way I look forward to future posts. THANKS
