Depends on what you mean by new: I elaborated on some of my core ideas about the field in the blog posts Why edugames don't have to suck, Videogames will revolutionize school (not necessarily the way you think), and also touched upon their role in society in Doing Good in the Addiction Economy. My thoughts have gotten somewhat more precise, but off-hand I can't think of any major recent insights that I wouldn't have mentioned in those posts.
On the topic of the educational game that I'm doing for my Master's Thesis, I'm making slow but sure progress.
Yes, I had read those posts before which is why I knew you were involved in the field. Good luck with your thesis - I think games have huge potential in education, but it will be difficult because educational games are aiming at a smaller target than normal ones.
