Whether you feel 2K17 is perfect now or just not good enough, I think most people will very much co-sign that maybe 2K should delay the release of the next 2K to until at least the start of the regular season (late October, early November) in order to get a better product out there on release date.
We'll probably still have 3-4 patches after the initial release of the next 2K game to iron things out like usually, but at the very least.........the gameplay issues that we experienced at the beginning of the year, it shouldn't happen as much again IF they just delayed the release another 2 months.
That is probably the downside to the new eSports deal that 2K just agreed upon with the NBA because now 2K will be expecting to release new NBA 2K games earlier than normal just to keep up with these eSports leagues that will now be made, and the gameplay will diminish further since they basically "revamp the game engine" every year when making a new NBA 2K game.
