Re:Er, that likely means they'll be on WP9 (Score 1)

But on a related-note, the first jump Microsoft made from Windows Phone 7.5/7.8 to Windows Phone 8 broke compatibility for all existing third party applications. That move really upset the early developers on that platform (especially when they had been told that MS was going to be different and was not going to be fragmented).

This is simply not true.

There was a single digit percentage of windows phone 7.x applications that were on market which would not run on windows phone 8.

Every other application required no changes what so ever to run on wp8.
