After reading the post earlier, one of the most intriguing things I walked away with are a possible new type of app.

• NEW Windows Phone 8.1 apps won't run on 8.0 devices until they upgrade

Is this a new, separate type of app much like when Apple released iOS 7 and developers remade their apps so they would be optimized for it? And since we already have trouble getting new apps to the platform and sometimes experience updates that seem to take months to be released does this do anything at all to alienate developers who have already jumped on and/or make those who haven't built apps for Windows Phone less likely to?

Just some thoughts, feel free to sound off.

Sounds similar to Windows 8 and 8.1. nothing to be worried about, 8.1 can install apps already made in 8.0, but the next time the Dev recompiled they will be using the new tools/layout options that work only in 8.1.

Windows 8.1 will be backward compatible. That is it will install both apps for 8.0 as well as 8.1. Just the same as happened for windows 7 phone and Windows 8. Also the new apps extension will change from .xap to something

From .xap to .appx what i've heard.

all the current WP8 phones shall be up gradable to WP8.1

#Toxid_Fox is correct. new extension for apps will be there as .appx
