So, Microsoft were first to reveal their 2007 Q4 shipments, we'll soon get Q4 data from Nintendo and Sony. In preperation I've searched through their previous quarterly financial statements and created the following shipment tables.

------ Q1: Q2: Q3: Q4: Total (M)
2005: ---- ---- ---- 1.5 (1.5)
2006: 1.7 1.8 0.9 4.5 (8.9)
2007: 0.5 0.7 1.8 4.3 (7.3)
--------------------------- (17.7)
Wii:
------ Q1: Q2: Q3: Q4: Total (M)
2006: ---- ---- ---- 3.2 (3.19)
2007: 2.7 3.4 3.9 ??? (9.98)

PS3:
------ Q1: Q2: Q3: Q4: Total (M)
2006: ---- ---- ---- 1.7 (1.66)
2007: 1.9 0.7 1.3 ??? (3.93)

Quarterly data is rounded off to the nearest 100,000. Yearly and Lifetime data is rounded off to the nearest 10,000 (excluding Microsoft).
