I know this topic has been beaten to death

but I would just like some clarification.
I want to buy a PS3, I have a 50" Samsung plasma (720p native with 1080i capabilities)
...Has the 720p problems been fixed with the PS3 or no? If so, is it just a firmware update or are they releasing new PS3's or "second-gens" that already have the problem worked out?
Again, sorry for bringing this up once more.
