Google talk on Android
Unless you're using Android 2.3.4+ (still quite rare), you won't even have audio on Google Talk, let alone video.
In fact, the HTC Flyer tablet is just about to get a 2.3.4 release and it still doesn't have video.
I've been quite happy with Skype audio on Android, despite the haters. I don't have a device capable of running the video in this release though, unfortunately.
I don't think Microsoft will have had anything to do with this update, but wouldn't care if they had, unless it was obvious that they were holding back specific features for their own devices.
