From memory of when I was talking to the AmigaKit folks at the stand, so this might be wrong, I think it's coming out in a couple of months.
I was about to ask them if they had any A600GS with them to buy... then realised the "A600GS" on display had A1200GS all over it :-D
As to upgrades for the A600GS, I don't know - one for AmigaKit to answer. We should find hopefully out more soon.
