I totally believe they will be available in stores at launch. The OP is incorrect to say that all we know is it's coming "later this summer". This is NOT what Apple stated. And since that's what they normally DO say when something is coming later, I think they'll be available on the 24th. All Apple said is that they white ones are unavailable for pre-order or reservations. I don't think they'll have a large stock though. So I'm planning to get to the Apple Store EXTREMELY early so that if the white ones are available, I'll get one. And even though I reserved a black one, I know they'll let me switch for white because they've allowed it in the past.
