So, Patrick Weekes, senior writer on ME3, had an informal review with a fan at PAX, and it's been posted on the Bioware forums. It's mostly all about the ending, but rather then another round of arguing over 'you suck/no you suck', it was more fleshing out a few details and such, some of which I suspect may be included in the planned Extended Cut DLC coming out sometime in the next few months. That, by the way, has been confirmed as a free DLC that expands the ending with more cutscenes and explanations, hopefully giving the players a better look at the end of the series then what even I admit is rather open ended.
