I'm preparing to run the Lich Queen adventure from Dungeon 100 in a couple sessions and it has a bunch of psionics in it. Some pretty cool githyanki subraces with psionics and new psionic equipment/items. I can't recommend it as I have not run it yet, but it looks pretty solid and I'm sure it will be fun.
One psionic adventure per year isn't a hard limit, but it's close.
Also, I'm talking about adventures that have strong psionic themes here. If an adventrue has one psionic creature in it or one psionic item, but is otherwise psionic-free, I wouldn't count that adventure against the general limit of "one psionic adventure" per year.
