While till today, we only knew regarding the features to come from Windows Phone 8 to Windows Phone 7.8 update was the New HomeScreen. And now, seeing the list, we actually get to know a lot from it.
There are now chances of a new lock screen coming as well, where you may be able to draw certain pattern on an image to unlock the phone. And if this comes, it will be much better than the typical grid lock that comes in Android devices.
There are also certain features are surely not coming to WP7.8. These include NFC, MicroSD, MultiCore Support, Wallet, and many more. We will have to wait for the official launch of Nokia World, in about three weeks from now, to see what features actually get added and what not.
