Completed all trophies, 250+ hours, all on my launch 60GB PS3.
Bugs and freezes encountered? countless.
But like I said,
"When you love a game enough......"
If FO:NV is anything like FO3, (Which of course it will be) I'm sure there will be some minor glitches and what-not. And I'll still be happy.
But what do you expect with such a large game world with so many NPC's and items strewn about? Everytime you move something, it had to record where you moved it to. Pretty much whenever you change ANYTHING in a game like this, it must record it. And thats why your save files get bigger and bigger with each save.
And, I think, for playstation 3 versions of the game (At least from my experiences with FO3 and Oblivion) with file size comes more bugs and crashes. FO more than OB though. I can start off fresh in FO3 and play for hours without having more than one small glitch, or maybe a crash. I found at later levels, and with more complete in the game world (Also with almost 14 MB of file size), there are ALOT more crashes and minor bugs.
For me (and maybe only for me), I expect a certain amount of hardships with glitches in Bethesda RPG's. Like I said before, I played Morrowind GOTY on Xbox only. XBOX ONLY!!! Somebody has to have went through that as well. But I've beaten it (and when I say " I Beat it", I mean EVERTHING that I could possible do is done) over ten times.
You have to love the game to still play after crashing four times in just a few hours.
I guess my point to all this is, I Love Bethesda RPG's, and a few bugs or crashes would never keep me from playing. I can honestly say that, I've never played a video game as much as the awesome games Bethesda puts out.
