OmniFocus for Mac - Should I Get It? (Yet)

I’m considering getting OmniFocus for the Mac. I’ve already got it for the iPhone and iPad. However, I’m a bit cautious, as it’s at version 1.9.4, so I’m guessing V2 won’t be too far away and I don’t want to pay the not inconsiderable cost only to find I’ll have to pay full price again for V2 in the not too distant future.

Any advice?

I don’t doubt it’s capabilities and I love the iOS apps, I just don’t want to end up paying twice in too short a time. If I knew it wasn’t coming out this year, I’d definitely buy V1 now.
