2K Sports is now on Tumblr with a weekly Community Update blog, the first post of which is by Chris "LD2k" Manning. He goes over E3 and writes some stuff about 2K13. Nothing new, but nevertheless a good summary of almost everything regarding NBA 2K13 at E3.

P.S. The way he capitalizes FUN twice (in the same sentence, mind you) when talking about the "waterfall" (seriously?!) controls, makes me think 2K really want to justify this ridiculous "feature", somehow.
