I wouldn't entirely trust that list yet. E3/E4 are the wrong way around for a start.
The official player list still has kubo with VSion (a month after it was posted), and during my brief exploration I haven't seen any posts from people who were there either confirming or refuting it.
Unless the Tougeki page is amended, or I get a first-hand confirmation of which character he was using, I'm leaving it as is.
Also keep in mind that there are still four team slots left, which are presumably due to be filled shortly before the final tournament. I'd think pretty much everybody with their name missing will be there.
