If Microsoft takes the same approach to displaying WP7 apps under Windows 8 that it takes to displaying them in the emulator for the development tools, resizing for different screen resolutions won't be critical.

The emulator uses the same resolution as a native phone (800x480 typical) which is quite legible on a larger screen due to the lower density of pixels on the larger display.

Apps running in the emulator are perhaps a bit oversized, but not untenably so.
