I've kept my expectations pretty much in check. So at this point, I'm neither extremely impressed or unimpressed. It's just simply too early to tell quite yet, imo.
Looks like several solid improvements are coming for M10. I feel pretty safe in saying...probably more improvements in one year than we've seen in many years...maybe ever. I do believe a full effort is being made this year, and I can't honestly say I've felt that way with past current gen releases.
My only real disappointment as of now is..that 2K seems to have a monopoly on smooth and fluid animations.
