I got my PS3 about 10 days before I got my HD baby. I would definitely say that you shouldn't be worried. Playing on an HDTV is nice, but Uncharted was JAW-DROPPING on our 10 y/o Sony flatscreen.
Don't feel rushed either, as buying an HDTV is quite troublesome. Check out http://www.vgchartz.com/forum/thread.php?id=96334&page=1 to see what I mean.
Hope this helps.
