FYI, here's the Playstation 1 (using the hardware shipment chart)...Numbers are from April to March of the given years:
94/95 - 830,000 (0.83m LTD)
95/96 - 3,430,000 (4.26m LTD)
96/97 - 9,240,000 (13.50m LTD)
97/98 - 19,320,000 (32.82m LTD)
98/99 - 21,600,000 (54.42m LTD)
99/00 - 18,500,000 (72.92m LTD)
00/01 - 9,310,000 (82.23m LTD)
01/02 - 7,400,000 (89.63m LTD)
02/03 - 6,780,000 (96.41m LTD)
As you can see, the Playstation 1's best year wasn't it's '3rd year', but it's 4th full year, and 5th Christmas. So it's entirely feasible that, if a console catches on later in it's lifespan, that it can do well and have great legs.
I am NOT advocating the 360 will beat 100m LTD (I think that's a cruel joke) but that it can shake off what most assume will be a lower year, and only increase it's current LTD install base by 50% from it's current LTD number.
Back from the dead, I'm afraid.
