I would think Sony would fix them, if your out of warranty and paying that is. I'd imaging that Sony has the tech to rebuild the bad flash with little to no problem. Then they have a bunch of older model referbs sitting on the self ready to replace older model PS3's. No more handing out newer models. Add to that, the YLOD will eventually claim those systems. Another 150$ and another referb from another brick. Hell, just swapping an unbricked system for a bricked system you can easily repair sounds like a cash cow.
Then again, they could move new systems by not repairing bricks. If I brick my PS3 during all of this and they don't repair it, I'll probably get an XBOX360 next. I'm still in warranty. Though I figured that didn't mean much.
All in all, the worse they'll do to you is refuse service and return your system. The worse they'll do to the community is keep your system, send you a referb and build a case around a one mile long four foot tall wall of bricked PS3 systems. I'd totally try to send it in. If that doesn't work throw it on Ebay as a bricked system. People will buy them for parts.
Never confuse heroism with simple self interest.
You must first be illusioned, before you can be disillusioned.
Hope is the first step on the road to disappointment.
