let the flames begin, I don't say this will happen, but I hope so:
DDR 333 RAM and bus
Firewire 1600Mbit (Gigawire)
60-160 GB HD
1-1.4 maybe 1.6GHz at least one dual config, maybe a quad, nVidia GeForce 4 BTO or top model, lower models GF3 ti 200. 3 USB 2.0 ports, 2 Gigawire ports, Airport option, Gbit ethernet, full keyboard and a 2 button wheelmouse (it's about time), new case bigger than the current one, yet still...
