I was thinking that we were going to get iOS 5.2 with Mountain Lion coming out in order to facilitate the greater integration between Macs, iCloud and iOS devices. But I recall that developers usually get beta versions of iOS updates. And I haven't heard of anything of the sort. So it's probably not likely? I know in the last previous iterations of iOS, it went all the way up to x.3 updates. It looks like with iOS 5, Apple is pushing out less of these.
