I think SCE is just fine, this will mostly affect the ailing TV business and such. Think about it. The PS3 should be being sold for a profit sometime in 2009 per Kaz Hirai's statement, and the 45/45nm chipsets are starting to be made in February, per whoever made them (IBM?), anyhoo, with the PS3 being ready to sold at a profit, not too much is going to change in the gaming division. They may shutter some poorer performing studios (SCE Cambridge - PlayTV, BigBig - Pursuit Force, Bend - Syphon filter, and maybe Liverpool, depending on how well the PSP WipEout games have done). And given how the NBA franchise doesn't pull in 2K and Live numbers (never seen it in NPD, but have seen the others), that may get axed.
In all, games that didn't light up the charts by studios may be getting closed. I'm not saying these games didn't sell good, as we don't have numbers on them, but I think we can assume that these games aren't as big as a Resistance or Uncharted. I think this may be the extent of any cost-cutting matters in this division.
But I'm no analyst, so who knows if I'm right or wrong.
