So Indy 4 starts shooting in June. Obviously, Lucas will be pushing for HD, while Spielberg will want to stick with 35mm. Spielberg's best argument against HD is that the resolution and quality are "not there yet."
Even the Genesis is only 1080p, which is not "future proof" since people will have displays at home surpassing 1080p within a few years.
As far as I know, the only HD camera that might work for Indy 4 is the Red. Dalsa is just too big.
Question for Jim and the gang: Have you guys been talking to Lucasfilm?
And don't plead the Fifth! :D
