Today at the Omni Group announced its expanded beta for the completely rejiggered Omni Focus 2 with a product release in June. The current beta is pretty complete. I started using it in the private beta about a month ago and for a few weeks now, it has completely replaced version 1 on my Mac.
The new version brings forecasting to the Mac and the Review mode brings the Mac a lot closer to iPad OmniFocus's utility. There is a lot to like about the new version. I particularly dig the way the inspector becomes a permanent fixture. I'll have a lot more to say when the final product ships but for now, if you're interested, get yourself over to The Omni Group and sign up.
