If we get these things ported at all, it will take time. Unfortunately, Touchwiz (the Samsung overlay on android that makes all of these features work) is completely closed source. This makes adding/porting features quite difficult. Basically, the developers here on XDA are amazing and continue to impress me daily, but I wouldn't hold my breathe for features to be ported from one device to another. Who knows though; maybe some great developer will prove me wrong.
