The 925/928 are the new kids on the block, and it may take a minute to embrace them...but I welcome them with open arms and a baked apple pie (or fresh screen protector and case...) Lol! Seriously, While it may be a defense mechanism for some, I think some 920 owners expected a "new Lumia" unveiling instead of a new Lumia 920 variant unveiling. Lol. The reality is that the "shelf life" of a smartphone's interest is about 6-9 months now. So ppl are ready to move on to greater things and a huge London event was probably disappointing for some.
On the other hand, Lumia 920 owners should be ecstatic that they are going to have one of the best camera apps available! They should also be proud to own a smartphone that won "Smartphone of the Year"!
