The PS4/Xbox One version of NBA 2K14 will feature the most up-to-date information possible.
Visual Concepts producer Erick Boenisch mentioned the following to Polygon about the next-gen versions of NBA 2K14:
In the [current edition of NBA 2K14], it’s like ‘Hey, the Lakers played last night. They lost 115 to 114. Kobe had a pretty good game.’ In this one, it’s going to be like ‘They lost on a last second shot. Kobe missed it but he shot 14 for 28. He had 31 points. Got in foul trouble late in the game.’ And that’s the kind of detail that you don’t get from the old system. Even when you’re playing the games, when it’s halftime, they’ll cut to games from around the league. You’ll get scores of games that are going on in real-life in the half-time of your local game.
This means while playing NBA 2K14, you’ll be up-to-date with real life scores as they actually happen. This will of course only occur if you have connected your console online and are playing around the same time actual games are being played.
