I'm hoping for a true Microsoft designed phone, not in the design of earlier Lumias. If they could just shrink a Surface: 6" 1080p screen, VaporMag, Gorilla Glass 4, stylus, mini-hdmi or display port, micro-sd slot, Qi wireless charging, & maybe even a built in kick stand. Plus, I'd love to see the new intel mobile processors just announced be included...making it the first device on the market with the new x3-C3440 chip. Put a whole new meaning to the term WinTel. Doubt that would happen, but I can dream I guess.
Truthfully I don't really need a new phone. I've got the 1520 and am 100% happy with it, but it Microsoft came out with something similar to the above, I'm in.
