Is BW2 already out in Japan or somethin'?
If so, then WHAT THE HELL I THOUGHT THEY WERE GONNA BE RELEASED ON THE THIRTIETH!!!11!1
If not, then what's up with the sudden onslaught of BW2 info?
The games are officially released on the 23rd but some people in Japan have received the games early and are playing through them, releasing the info as they go.
The games launch on the 23rd. That means they get shipped to stores earlier (today) so they can be readily bought that day.
Which means that some people've played one of these retail copies. Generally speedrunning the thing and posting everything on the internet.
