Please accept our apologies for the delay in the release of the templates for Windows Phone 8.
For now you can use your Windows Phone 7 application, right click the solution in VS2012 and select Upgrade to Windows Phone 8. This will spare you the setup of your app from scratch and let you continue with your Windows Phone 8 app just where you left off with WP7. The other option is to check out the source code of the Design Templates Showcase application which is available as part of our Integration Examples which you should have along with our latest release.
