2K UpdateSomeone who's very clever sent me two notes about my 2K Sports post yesterday, and it was noted that:
1) Kush was replaced after MLB2k8 last year--they no longer develop sports games for 2K Sports (although a fair number now work for Visual Concepts, so it wasn't a complete turnover).
2) The biggest changes in the last few years have occured with QA, not development.
#2 is particularly interesting, and it's correct. After NBA2K8, it looks like QA was moved to 2K West and away from Visual Concepts.
