The spikes in the graph I linked to for the PS2 weekly sales/shipments sit at 1.76M units per week at the highest in its popularity on 12/22/2002, surrounded by solid weeks of 1.45M, 1.41M, and 1.22M. That's 5.84M in one month WW, not to mention the 400-700K it sold each week in November, and 270-330K each week in October. For the quarter from October 1st to December 31st, it was about 10M units.
The Wii has proven to be selling faster than the PS2. Trying to match the Wii's expected first spike against the PS2s second and largest spike may not be accurate though. The PS2's first spike in 4th quarter 2001 was 7.6M units. That's still quite a bit more than I've seen projected to be available for the Wii for the same quarter.
