Yeah, I did that too. I'm figuring NVidia won't add it until the next drivers and GeForce Experience are released. I don't think it's going to be a huge seller out the gate like GTA 5, where they release a new driver for it the day of it's release.
Either way, with the pc version of it, we get all the Xbox One & PS4 modes included in it. We also get all the dlc free.
I've got a Xbox 360, so I only got the dlc and modes available to it.
Now that 2K has put the WWE games back on pc, I have no needs for a Xbox One or a Xbox Live subscription.
I can pick up a blu-ray player cheaper than either Xbox One or Xbox Live would be and utilize WWE Network, Netflix and Hulu Plus! on it, for a lot less money.
