It's not just this. The lack of a clear plan/solution for going forward regarding the new Xcode/IB single IDE; the solution to keep using the previous version just isn't ideal. I've seen a few times in the past 6 months where major changes dropped and users were asking for really basic info/response on forums and got nothing. I'm just going to stick it out with obj-c.
they have already announced that they're working on xcode 4 integration, and just today one of the developers for MonoDevelop released a video showing that integration working.
Good to know, but poking around the monotouch website I don't see anything about this. I'd think this would be on the frontpage or the news section at the very least. Nothing about it in community either. Little things like this (not being able to find valuable info) really does kill motivation to work on this otherwise fun/interesting platform.
