What the others have said...
I don't even mind it if they 'simplify' some stuff for space reasons. I know the Mindlink power from the XPH has been reprinted in other books (for those that don't have the XPH) and it isn't quite the same. I don't have the books in front of me so I'm not sure what is difference is (I think the reprinted stuff doesn't have the exansion ability for extra power points - but I 'm not sure).
That's fine - maybe even better. If I have the XPH, I have the full ability. If I don't have the XPH, I have something to work with. It may not be the full ability but it also doesn't take up more space than is necessary.
Now... I'm not saying that I want WotC to say 'buy the book for bonus material' or something like that. Putting a Sword Sage into an adventure with the stances and maneuvers listed is great, then for those without Nine Swords the Sage's abilites are simply 1 per encounter. For those with the book, they will have the info for refreshing the maneuvers. That, I'm fine with.
