At some point feedback is good but again, criticizing what we saw last night is akin to criticizing the rebuilding of a highway after only one of five lanes is finished. Sure, we could say, "Hey, um, you guys still haven't finished the other five lanes yet" but that probably wouldn't do a lot of good at this point. What we saw last night was still essentially 2K12, so any issues people have are likely already addressed in the Wishlist thread.
I'm not very knowledgeable on game development. However, I do recall many instances in the past where videos would be released in September and those would be from 2K builds that were multiple months old. Assuming this 2K13 clip wasn't just played up from a version of the game completed on June 3rd, the build we saw could easily be from May or earlier. Considering the game doesn't go gold (submitted for completion) until mid- to late September, I'd say just about everything possible has the potential to be added and adjusted. To assume nothing will change because it's too late in the game is way off base.
Regarding mid-August (as you brought up), I recall changes being made at that point and likely even later. Prior to 2K11's release, even small details were being adjusted right up until the end. For instance, Michael Jordan initially had a deep purple tongue. That was noticed and changed. In 2K12, LaPhonso Ellis' rights were secured in September and he was subsequently added. Further, when the demo for one of the recent 2K's was released (2K11 or 2K12) every layup (even breakaways) bounced off the high glass before going in. That was also acknowledged and adjusted prior to true release. So I feel if small stuff can be altered deep into September, I'm certain big stuff is going to be happening in May.
That comment is clearly open to interpretation so I can't fault you for taking it the way you took it. However, as someone who lived through ESPN NBA Basketball 2004 (2K's sequel to NBA 2K3) I interpreted that comment as him saying 2K wasn't going to drastically change the direction of their game. Nine years ago, NBA 2K3 was a simulation on the rise, so what'd they do for 2K4? They changed the name and essentially turned it into a dumbed-down streetball contest featuring double pump reverse dunks via Elden Campbelll at a standstill.
So again, to me, "more of the same" means they're going to try to continue making an excellent NBA basketball simulation. I honestly don't think he was trying to say, "Welp, our internet connectivity was pretty much non-existent in 2K12. As such, many of the features we lauded, such as dynamic art updates, YouTube uploads, and Pressbook shares, barely worked or flat out did not function. It sounds like the fans absolutely loved that so we assure you, we plan on more of the same. This year, we plan on making things work even less good. Yes, you heard me right, less good. So keep an eye out for that."
