I'm glad they're releasing power cards and I'm not at all sure, they've planned this all along.
While I am pretty sure the
WotC cards won't be as good as some of the fan-made ones, I'll still prefer the
WotC ones if they're sufficiently sturdy. My problem is not having access to a good printer. Printing them at a professional print-shop would _definitely_ be more expensive than 10$ per set.
I won't buy all of the sets though (at last initially), only the ones I actually require to play my character(s).
