A/V,
Sounds like you have the budget for some major HT upgrades.
For the projector, check out the new Sony "Pearl" model for 1080P performance in the $6k price range. Hopefully the bulbs will be cheaper, too. To take advantage of 1080P front projection, you should consider a larger screen in the 100-120" range. You might buy the projector first and point it at a light colored wall to evaluate the best screen size.

If you are happy with the current Klipsch reference speaker, the new versions will probably be more of the same. For an upgrade, check out the new Klipsch THX line for HT. If you plan on a lot of music listening, then the Paradigms or B&W might be better options.
I am not sold on the HD players, but the gen 2 players comming out this year are finally starting to include the main benefits of the new formats like 1080P, HDMI 1.3, and Dloby True HD formats.
Don't forget about room treatments for your high end system. Light control is also important for front projection.
