I'm going to hope for some information on the Fire Emblem crossover and of course Xenoblade X. Of course, I don't actually think they will be there, I just hope they will be. If there is anything Xenoblade related, it will probably be about the New 3DS port. I do think Splatoon will be there though, and it should be interesting to see more of that.
Just thought I would point out that PC isn't immune to this either. That same group was "attacking" ncsoft too. Of course, the only problem that caused was I got kicked out of Aion for a few minutes a couple times. When it is just a DDoS, I kind just go, "Oh, haha, that's cute". It's not like people's credit card information are getting stolen.
