Searching for anything on this resulted in coming across http://www.shawnhargreaves.com/cv.html where he is no longer on the team from 2010, however I couldnt find anything in his 2010 blog archives mentioning this (although I focused more on titles oppose to content), mind you there was a blog about him getting married in 2010 so not being part of XNA could be because of that.
As much fun as it is playing detective, it is giving me a headache, maybe I should make a XNA game called "is XNA dying" and design it like cluedo
Personally I dont like portable crap, phones, tablets, laptops etc but I will likely make use of DirectX 10/11 and assuming XNA does live for the sake of Xbox 720, it would be a long time before that comes out.
Anyway thanks for the reply, I think it is time to move on, at least for me anyway
