Windows 8, Windows Phone 8 Application size limits

Question

Is there any information available regarding application (xap) size limits for

1. Windows Phone 7 = 225MB
2. Windows Phone 7.8 = 225MB?
3. Windows 8 (Metro)
4. Windows Phone 8

Answer 1

The size limit for a Windows 8 Metro style app package is 2GB. See Package Format Requirements. I do not believe there are any details out there yet about Phone 7.8 or Phone 8 in terms of XAP size.

Answer 2

The size limit for a Windows Phone 8 is 1GB according to 4.1.1 of the app submission requirements, found here. This was last updated a week ago (Dec 12, 2012). Nothing was specifically mentioned for WP7.8, so I assume it's still 225MB.
