I got to try on all the new Skate Classics at the store I work at today. Some points:
-New insole is firmer and flatter, Old Skools and Authentics feel like most vulcs now. Less squishy feeling shoes in general.
-The Sport Pro feels like a Blazer to me, really looking forward to skating it.
-The Slip-On is very tight fitting now and the toebox is narrower. I personally found it too tight, break in will be awkward.
-Half Cab is dead, they killed it. sorry lads.
-If you like the Sk8-Hi you'll probably still like em.
