Nintendo- Massive profits, great sale of old games(pure profit), WiiFit and SSBB massive sales too, great sales for SMG and TP. Makes a boatload per Wii and DS sold, and they sold a lot of each.
Sony- no major 1st party games, higher than expected HW sales(means more loss) - software sales not good in comparison to hw sales, possibly due to blu ray buyers. A loss, not to huge. But a loss.
Microsoft- making slight amount off each console, good 3rd party sales, no major 1st party sales (except legs for a few games... I can them making a profit this quarter, not a huge one, but a proft.
Also I am pretty sure the DS Lite was released at 129.99 and was making a proft then. I have no figures for this but I believe Nintendo could sell a DS for 79.99 and still make some profit, or a least break even.
The Wii was making 50 dollars per console at launch, I would guess that the profit margin is a LEAST 80-100 now, or more. I think if Nintendo wanted to they could sell the Wii a around 149.99 and break even, or be close to it.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
