It is not difficult to compile a 64bit windows version, since most of 
the dependencies are available from gisinternals( 
http://www.gisinternals.com/sdk/ ).
The difficulty is more in the detail:
- GRASS : I don't have experience with compilation for 64bit
- Formats like sid, ecw
- Interlis support (important here in Switzerland)

Therefore I think it would be best if osgeo4w could have a 64bit version.
