Along with this came the reminder that the next phase of the beta will include PC/PS4 cross-platform play so that should be fun.

I thought the next beta was PC only? Or did that already happen?

I was not aware of any plans for a PC-only beta

Not surprised by these requirements. I'm eagerly awaiting more information on the beta though. I still haven't preordered but I likely will for the PC beta.

Did the PS4 version work eventually? Like online and everything?

@brake: Although it was rough early on the few matches I played of it were playable. Some videos of the last beta looked like most of the matches were lag free. Not sure about the wait time on matches though.

@riostarwind: @brake: Beta worked fine eventually, matches were laggy a fair amount of the time as you'd expect from any fighting game; certainly wasn't a revelation in lagfreeness. Wait time was really inconsistent, sometimes 30 minutes to an hour sometimes every 5 seconds.
