Windows Phone 8 - Just the bullet points

This is what I heard

• Shared Kernel with windows 8 based on NT rather than CE
• Multi core CPU support up to 64
• hd screen resolutions: WVGA, WXGA 720p 
• NFC Payments and loyalty cards 
• SD Cards
• IE 10 browser
• Nokia Map Data with turn-by-turn navigation
•  enterprise features: encryption, secure boot, it management
• New Start Screen with resizeable active tiles
• share info between phone and other windows device (Like andoird beam)
• in App Purchases
• Deep Skype integration

and the killer No upgrade path for ANY legacy devices but as a sop there will be a WP 7.8 although all I can find about that is that it will be an OTA update and include the new start screen
