Well, the problem is is that you don't speak for everyone, because I doubt the entire community has the same exact opinion about things like graphics or where the team should focus their time on. I think the graphics are pretty damn good for HL, and I'd be impressed to see them make any drastic improvements given the limitations of the aging engine the game's based on. The only confirmed thing that's going to be looked at in 1.3 is transformations as far as I know. I'd imagine that other things are going to get done, but whatever it is, I'm sure the team already has a plan set for it. They haven't done anything wrong yet, so I'd just sit back and enjoy what they present to the public free of charge.
Only time will tell.
