928 is a hell of a phone. If you consider waiting for the 929, why not just wait for the next model or the model after that? There will always be a new and better model on the horizon. If you go that route then you'll never be satisfied.
But, the 928 is the first claimed "high end" one on Verizon. The 929 might of ironed out all the bugs with the 928. To be honest, I would wait for the 929 or to see what HTC releases (A rumor of a HTC One with WP on it sounds very cool).
On that note, if you wait for the 929 to be released, the 928 would bottom out in the pricing, so if you have the 8X, live with it for a few more months till the 929 is out after a few reviews to see if that is what you want. If you still want a 928 at the point, you should be paying almost nothing for it as they will be really cheap after the new model is released.
928 no question is a really nice phone with a great camera WHEN it is working fine. The problem is when I need to be doing something that I feel is important at the time, is when it locks up on me..
As for the screen stoping working, look at my other thread about the issue....I am not the only one with this issue...
