MS is setting itself up for disappointment.
Going by the SDK leaks on winunleaked there aren't any big surprises left. Everything about WP8 seems to be known. A lot of the things people have complained about in WP7 are unchanged. E.g. volume control or multi-tasking, which seems to be identical to WP7 but now reportedly with seven apps instead of five.
(WP8 is already a really huge under-the-hood update, so it's not that surprising that they didn't tackle every little issue people have with the OS; the things they did add like lenses, voip integration, backup functionality, maps/navigation, and rooms will be great, though)
There are lots of complaints about MS not revealing anything and not releasing the SDK.
The verge and other sites will criticize WP8 for all the same reasons as they critisized WP7.
Now there's allegedly a chance Nokia is going to sue HTC (see
http://wmpoweruser.com/report-nokia-to-sue-htc-over-lumia-windows-phone-device-designs/). You'd think having more WP support and more really nice colorful phones out there would be good for the ecosystem and mutually beneficial for Nokia and HTC.
I really really hope WP8 will do well and get more support from carriers, OEM, better marketing... It just deserves to do well.
