The fact that the two versions will be different is also evident when considering the fact that the PlayStation release will support the PlayStation VR as well, and this alone will probably take a while for the developers to implement.
With that in mind, it could be more reasonable to expect to see the game a few months later for the PlayStation 4, and by that time the console version could also incorporate some of the information that will come about from the development of the arcade version.
After all, we expect that gamers will find plenty of bugs and gameplay problems during the testing and possibly even after that, and the developers of the PlayStation version of the game will most definitely be keeping a close eye on those developments so that they could fix the other game more quickly. Gamers planning to get the PS4 version should keep an eye on the arcade one for potential hints about the balance.
In a title like “Tekken”, proper balance and a glitch-free gameplay are crucial to the longevity of the game, as its competitive nature means that even small issues can become disastrous when they manifest in the worst possible time. It’s never fun to lose a competition due to a glitch, and Bandai Namco are known for their attention to quality and details, so we expect that they would do everything in their power to prevent that.
