While Sony must be very disappointed in how badly they are faring in the handheld arena I think they still must be happy with how the PS3 is performing over the Wii. Maybe the biggest overall concern is how badly the home console market is faring vs handhelds.
Also PS2 can catch 360 in the YTD, I believe!
i think sony doesn't really care about how the ps3 is doing against the wii when the two have been a lot closer than usual lately. it's not like sony makes a lot of money selling their own ps3 games, so having a big userbase at this point is only good for gathering support for the next generation. with companies looking at the west, i'm not sure how this helps them.
