Here we go again guys. A promise. A promise not just made but delivered on by Microsoft and xbox. Microsoft will unlock the retail version of the xbox one as dev kits like they promised starting this year.  Every announcement at GDC has been huge for Microsoft. And what I love about them is that they are mostly announcements that are about this year stuff and coming surprises not stuff hoped for, delayed further, or lies. Something Playstation could stand to learn a thing or two from them.
