DUDE. (haven't got the phone but, trust me, I've watched enough vids and seen enough pics)
The screen is......superb, to say the very least. The SUPER AMOLED PLUS, is SO vibrant and really does make things appear as if they are more real than any mere "LCD" or even "S-LCD".
And the "plus" bit of SUPER AMOLED PLUS basically has been made more efficient and has a 50% increase in sub-pixels, which basically results in the phone looking like it has more pixels. (At least I think so)
If you got to any competent website, that compares the 800x480 Super AMOLED Plus with qHD, they'd say the Super AMOLED Plus is better.
Also just a personal opinion, with qHD, apps are going to be streched and look very ugly. (OF COURSE, they will be updated, but how long will it take? I'm still getting updates on my iPod Touch saying..."now retina ready"
I just wouldn't like to see that beauty of 4.3", but then some pixelated stretched apps....ewwww.
If you STILL need proof, go to the link on youtube and watch in 720p, full screen.

And you'll see the screen, cannot do any more justice that it already does.
