OK. I say never because a follow all MacBook Pro launch date (check Wiki's). Apple never released a MacBook Pro in July, Augustus or September.

It seems Apple have
- early : January, February, March
- mid : April, May, June
Never spot any launch in july, augustus or september.
- late : October, November, December
Only the 2011 MacBook Air was launched in July.
BTW, it makes sense. July and Augustus are summer holiday. If you check worldwide high tech sales (including laptops), it's the lowest sales period.
PS : It's only IMO. Perhaps Apple will be in a hurry and wants to be within the first.
PPS : Also, due to PCH bug, I think Apple will wait new stepping coming only in mid-July according to mainboard manufacturers.
Well, there's a first time for everything. Also, consider this, the plan was for a June release, like last year. But then Intel had to push back their release date for Haswell. So Apple will ramp it up when they get those chips in early June. You gotta figure the machines are in production, just waiting for the chips. Also, there's a huge group of students that are waiting to buy their back to school computers here in the U.S. Mid August is my guess
