Trulyshy, this isn't really the kind of answer you were looking for, but I don't know of any plans to not do that feature on the phone. I can't promise it will happen in any given timeframe, in other words, but I can promise it's possible that it will happen at some point. :-)
I'm not sure how we'd shrink that view down to work on a phone-sized screen, but if folks let us know they want it, we can certainly think about ways to do that. Email
omnifocus-iphone@omnigroup.com and let the support ninjas know you'd like to see forecast view come to the phone. Thanks!
(Tweaking your title to make the thread more findable by other folks that would like to see it added...)
