I`d suggest to wait for the new Nokia WP 8/Apollo high-ends, most likely with quad-core processors and PureView cameras...I guess that really could be something, as Windows 8 for PCs certainly doesn`t look bad and these phones should be "the most seamless transition" between the phone and a PC so far...
they should be announced in late 2012...

That read and said, I can easily stick with my N9 for another year...
