Every leak list had Juri, so I hope they announce her soon.
After SDDC, we can expect another announcement at EVO, right ?
Also, about the beta, can we play indefinetely or just a few hours determined by Capcom to test their servers ? I really want to make the pre-order to get the beta, but not to play only a couple of hours and the wait the release.
It's entirely possible all the leak lists could be complete fabrications and she's not in. That being said, I think her chances are rather good regardless.
I think we can expect announcements at every upcoming event Capcom will have a presence at. I think this is part of why they haven't revealed too many yet.
The Beta starts and runs for 5 days. I am assuming it will be available to play that entire period. If you don't want to get locked in with your preorder use Amazon and cancel later if needed.
