Blu-ray on 720p Sharp projector?

[Chevypower]

There is a problem with 1080p projectors right now. They don't have any lumens.... Yeah I have heard the talk before, ANSI lumens means nothing, it's all about the contrast ratio. Well I need something with a bit of both, and to get both on a 1080p, you are looking at $40k-50k. At least on a 720p, you can have about 2700 lumens and 1000:1 or more contrast relatively cheap.
I am sure it won't be long and you can have a 4000 lumen 1080p projector with good contrast. Interchangeable lenses would be good to, to alternate long and short throw.
