Oh, I suspect there are going to be at least two total redesigns, maybe three or even five. On the block:
13" MacBook Pro
16" MacBook Pro
27" iMac
Mac mini
Mac Pro
Any one or all five of those things could get hammered on Monday, and all are due for major redesign action.
FYI: Two laptops aren't going to use up 1.5 hours, so expect some AS talk, and something special.
