I'm not sure what you're saying. I think they may be working their employees more due to their help with 3rd party devs, and I think they may have even been hiring. But then again, they also just merged themselves with the (walkman or ericcson) group I can't remember which.
I think their employees are probably paid solely from the profits of the ps2.
EDIT: Pristine, yeah that's what I didn't get about his post. There may be increased costs from development and R&D, but a lot of costs for payment have already been considered. Even dev costs are incorporated into the margin of their games. Which is why they only make like 30 or so per 1st party game. Most of everything is accounted for already except for the increased costs I mentioned like paying for marketing, third party development, and new R&D
