You can always run OmniFocus in double-pixel mode on your iPad. You just use your regular OmniFocus app but it's just resized.
Various interviews with Ken Case has an estimate of end of year 2010 for an OmniFocus app that is redesigned for the iPad.
Remember, CulturedCode only has one app to work on.
OmniGroup has OmniGraphSketcher, OmniOutliner, OmniFocus, OmniPlan, and OmniGraffle. They have their hands full.

So it looks like Sketcher and Graffle made it out first. OmniOutliner iPad, OmniOutliner 4, and OmniPlan 2 looks to be next in line. Then finally OmniFocus will bring up the rear.....
In the meantime, I'm still happy with OmniFocus on my iPod touch. I can see myself carrying the touch way more than I would be carrying the iPad.
But, yeah, I would love to see OmniFocus on the iPhone/iPod touch earlier....
