Nobody can answer that specificially but MS and Sony, as they have other things in their respective divisions.
However since the 360 debuted, the EDD division has made a loss of $500-$700 mill overall. They've made $1.3Bill in the last 12 months, so in the next 6/9 months they should erase that $700 mill and the Division will be in profit since the 360 Arrived. (X360 is in Entertainment and Devices Divsion, which is Windows Mobile, Gaming)
For Sony, the division includes Vaios and such, but they've just this Q lumped everything in one division, TV's, Vaios, Playstation, PC ect, so from here on out it's gonna be virtually impossible to figure out how the PS section is doing, yeah thanks Sony! Anyway Since PS3 debuted the division as it was has lost about $4.9B, this is with PS2 and PSP supposivly making profits (well you'd assume) So PS3 losses could be higher, unless something else in the division has made a heavy loss. I guess PS3 losses can be anywhere from $4 - $7 billion
