I am certainly going to pay close attention to this phone....
My upgrade is early September, which means the Bionic, GS2, and this phone are my main options:
Each has my interest, and I will almost assuredly get one of the 3.
Prime: Has my interest as for all intents and purposes it appears to be a GSII with a bigger screen, is going to be LTE , and has stock Android. This lines up perfectly with my needs/desires on paper. It will need certain things for me to be serious about the phone, however. It can't come out after October, because I'm tired of my BB Storm after my D1 died, and simply won't wait that long. Also of consideration is the feature on the GSII to tone down the color saturation, which the Amoled Screens annoy me with. Finally, I really need to hold this thing as a 4.6 screen might just be too big, when I feel that 4.3 is already pushing it, even if one of the main things I will use the phone for is watching movies/videos during my train commute. Also battery life on a 4.6 is a big concern. Finally at least enough storage space to rival the GSII
GSII: This is my #1 choice at the moment, barring the Prime being released in a timely fashion, or this phone not being LTE. If this phone is LTE confirmed, and the Prime releases at the same time, it will mostly come down to the likeability of the 4.6 screen
Bionic: I don't like the pentile screens. They're too washed out, and -I- can see the pixilation on solid colors. That said, if the GSII does not come with LTE, and the Prime isn't around until Xmas, I will get this phone..
