Cool phones with the same unibody looks as the 920, but where does this leave 620 and 820. Surely if these are so similar in spec but cheaper, that is a bit of a kick in the nether regions. The 520 even looks to beat the 620 in a few areas. On the other hand, the 720 could be my perfect phone, I am already in love with the 820 and the 720 looks like a great step into windows phone 8 from my current work HD7.
