Heh, you're right. Right now film definitely has the edge in resolution. If you're talking IMAX, then film will have the edge in resolution up until 4000x3000 or so. The problem with film is the degredation with each generation (digital has none), and jitter (again, digital has none). Because of this, your typical digital theater will give you a better experience than your typical film based theater on digitally produced pictures (ie. EP2). There are definitely exceptions though, and a digital theater can be poorly set up just as a film one can.
Right now, the best digital projector is probably JVC's QX1 D-ILA projector, with 2048x1536 resolution. It's extremely difficult to match the quality of this projector when fed 1080 images through a Teranex. You have to go up to IMAX to do it.
