Do you think the number of phoneapps will rapidly increase if they are compatible with windows 9?
Curious about your opinion!

No.

There have been no indications that Windows Phone 8.x apps will not work on WP9. Would be rather silly if you ask me. I don't think Windows Phone 9 in and of itself will make much of a difference. It's a matter of what platform Dev's want to release on.

Now, with WP8.1, they did make a change in the way the apps are packaged and deployed, but it would not be a major thing to get older apps updated if the dev's put a little time into it.

That's asking a lot, lol. Especially when most devs can't even keep their apps updated and working properly, or with the latest features.

But I do agree in that I think they'll keep current apps at least compatible with WP9.
