I'm not sure that Apple is really going to devote that much attention to the Classic over the coming years; actually, I'm with Beric, in that I fel the classic may well be discontinued as the capacity of the touch increases and as SSD drive technology improves. This would be a pity, as I, for one, love the classic, it's superb battery and excellnet capacity. Re the actual question, I don't expect to see much, if anything, over the next while.
Cheers
