Jmoney - Ehh, regrettably not, I would make a separate mode where they're all singles again (since a fair few people also like the varied fights) but then that makes me need to upload four versions each time and that's just urgh. If all else fails you could probably just change them back yourself with a trainer editor or something, I guess...
Tick - Heheh, I see. Don't worry, they aren't forced in SG/SS by any means. I guess I'll have to wait and see how different B2W2 turns out to be from BW, though, since it might be worth an upgrade if it's sufficiently different to warrant still playing BW.
Nxenz - No, no date yet. A total estimate would put it around the 24th or 25th of May, but I cannot stress enough that that's just guesswork.
