I think its a good idea for a high end model Tv. yes it would be expensive but its not like they will stop making the standard ps3.
those saying what it the ps3 breaks. you get it repaired by the same guy who would repair your tv cause its part of the tv. when my samsung hdtv crapped out i was able to use the 2 year warrenty that came with it (a year longer than ps3's warrenty) and samsung sent a tv repairman that seems to have never repaired this version tv and he came with instructions on how to repair it. the same can be done with a tv with a built in ps3.
Im pretty sure we will soon have tv's with built in blu ray drives so it all comes to having the ps3 mainboard added to the tv's mainboard. The Tv will already provide the power supply and cooling that the ps3 needs.
I wouldn't be surprised if 2 years from now when the ps3 will be cheaper to produce to see it built into a few sony model Tv's.
