@OP:
The best thing for Sony wouldn't be to branch PS off, but to be taken over by another Japanese giant, that should cut what is losing too much money and possibly join Sony monitors and TVs with another brand to keep the former alive as premium brand of the latter, with the necessary synergies and production volumes to achieve economies of scale and keep costs under control, without Sony needing to stay anymore in the lower market segments, where it can't really compete. The same could apply to optical drives, audio-video and PCs. Probably this way the new owner shouldn't cut any Sony division, but simply ditch their low ranges that would be reserved to the other electronics brand it alreaddy owns. There are many Japanese keiretsus powerful and rich enough, in a good relationship with Sony, and owning well known electronics brands that have a good reputation for quality but aren't luxury brands, so the sinergy could work quite well. It would also be good for the whole Japanese economy, as with Sony in a quite bad shape it's giving away to Samsung and Korea large shares of a very profitable market segment without fighting effectively.
