I agree, Apple is unlikely to change the form factor for a revision two. I would go with larger SSD (though 64gb is the limit today, there could be improvements, but a switch to SATA would probably be needed, along with the current SATA drive shrinking in physical size), I would say a jump in processor speed is not out of the question, improvements happen all the time. I don't think 3G is in the works, I don't think Jobs really liked being forced to team up with AT&T, it was more a marriage of convenience. AT&T was hurting enough to agree to many of Apple's terms, but we don't have bluetooth tethering yet, which is common on other carriers, but expressly against AT&T's terms of service. I think the inclusion of a 4 pin mini-firewire is possible, just to appease the "Where's the Firewire?" crowd.( they put FW800 in the Macbook Pro after they took it out, so change can happen) They will also probably do a BTO RAM option with 2Gb being the stock, but with a hefty price upgrade to 4Gb (all being soldered on). Other than that who knows what Apple will do, they are a very unpredictable (innovative) company.
