I think there are quite a few reasons why WP8 is getting more attention nowadays. From what has been reported on many sites, a lot of it has to do with the fact that carriers are getting sick of paying huge subsidies to Apple to carry the iPhone. When you're putting up $400+ in subsidies per device, that definitely takes a cut out of your profit margin. Android provided some relief from that in being the first true iPhone competitor, but now you have a million devices running various overlays on top of the OS and I imagine it can be a headache for CSRs to troubleshoot all of the issues that may arise. With the carriers looking for a third OS to endorse, the fact that BlackBerry is dead in the water until Q1 2013 definitely makes WP8 the front runner.
As to WP8 itself, it is a closed OS like iOS so there is less chance that a user will brick his phone modifying it and you can troubleshoot WP8 devices in a much more common manner than with Android. Also, with Windows 8 switching to the formerly-known-as-Metro UI, buyers will be familiar with the OS when they are looking for a phone. Microsoft made a very smart move by linking their desktop OS and phone OS so closely together. Windows is by far the most commonly used PC OS so it's almost like free advertising right there.
I'm almost positive that my money will be spent on a WP8 device in the next couple of months for the following reasons:
-iOS, while arguably being the smoothest performing OS, does not offer anything that interests me as I hate the fact that the UI is essentially a big app drawer with no real way to modify it without jailbreaking. I have no use for Facebook integration, all of the major OSes will offer turn-by-turn navigation, and Siri is not something that I would use. Unless they have a huge surprise at the iPhone 5 (or whatever it will be called) event, Apple won't be getting my money even though I have purchased quite a few apps up to now.
-Android has a small chance of getting the nod if Verizon gets a compelling Nexus device that will be updated as quickly as the GSM versions. I have money invested in that ecosystem as well but from now on, it will be Nexus or nothing even though the Galaxy Nexus was a disappointment with its horrible battery life and reception.
-BB10 actually looks like it could be a true contender if RIM survives to release it. While I'm no fan of BB7, I owned a PlayBook for a while and for being a consumer beta test it was a huge breath of fresh air. The video footage RIM has shown has only reinforced my feeling that they are definitely doing something right. My main concern would be their reliance on the BES/BIS platform for e-mail. As a non-corporate user, I hated not being able to see all of my e-mail folders and the lack of advanced functionality was a killer. If I hadn't sold my Galaxy Nexus to maximize what money I could get out of the device, I would almost consider waiting to see what RIM does release. However, RIM faces the same burden of public opinion of their OS that Microsoft did when they went from Windows Mobile to WP7. For years, all I heard was that WM was junk and I never even looked at it to give it a fair shake and quite possibly could have done the same with WP7.
To end this rambling post, all I can say is that it's a great time to be in the market for a smartphone. The next 6 months will see some really great devices released.
