Canon 1D Mark IV Pro DSLR Revealed Tomorrow?

Canon's pro DSLRs are Holy Grail ancient at this point, so something's gotta be coming soon: It might the 1D Mark IV, as early as tomorrow. People, inventory systems and invitations are talking.

The rumored specs are for a 16MPish APS-H sensor (1.3x crop factor) with bursts of 10-12fps, 19-point autofocus system, and the same kind of 1080p video powers as the 7D. Price? $5000.

Even if it's not tomorrow, it can't be too much longer before we see some 1D and 1Ds Mark IV action, since Canon can't let Nikon have all the pro fun, after all. [Photography Bay, Canon Rumors]
