According to WPCentral, Microsoft has put out an employee job listing. It looks like they're gonna be Testing WP9 soon. It doesn't mention anything about if it Is the Windows Blue Update, or after the Blue Update. [Windows Blue is supposed to be an Update, that lets Apps be made for W8 and WP8.]

Very interesting. [I find it very hard to believe they would just do 3 typos, in one job listing.] It looks like Microsoft might just have a solid 5 years ahead of them. Windows 9, WP9, and Xbox ∞: might just be pretty amazing, coming soon. :) Thoughts?

With the core change for Windows Phone 8 I hope my phone is able to get the update, if not its back to IOS for me.

@personauser: It is to get the update! :D
