Nintendo obviously.
Microsoft... They have generally been posting profitable quarters and I can't think of a reason why they wouldn't this time (unless they have had a price cut?)
Sony... They posted profit last quarter, but that was Christmas quarter (and they posted profit the previous Christmas but that didn't stop them losing money in the Jan-Mar quarter)
tough call for Sony, as the PSP doesn't seem to be helping them much anymore, and PS2 profit is waning, so it depends on how much the PS3 software, which is selling quite well, can bring them up. (and as usual how much of a loss they are making on PS3 hardware, if any anymore)
Edit.... actually it may be difficult to tell with Sony anyway as they combined the gaming division with 2 other product lines didn't they (Vaio was one I think, was the other the walkman line?)
