WPCentral figures out the 4 resolutions for WP8

Windows Phone 8 Apollo will support these screen resolutions:

Widescreen 15:9

1280x768

800x480

Full screen 1:1

768x768

480x480

The full screen devices will be BlackBerry-esque messaging devices. The low resolution devices will be targeted at emerging markets. Getting apps to fit these screen resolutions will be very easy because the app only has to zoom 2.56x going from lo-rez to hi-rez in either widescreen or fullscreen.

Full explanation here.
