I like it too. They're not setting themselves up for huge disappointment like some sad people around are...
Oh, I'm perfectly fine with people losing hope. I've lost hope already. The thing I don't like is when people are going out and saying "So and so isn't playable" when there's NOTHING indicating that at all. Saying "I highly doubt someone is playable" is one thing, but blatantly saying "Nope, no new DK content, no new DK characters are playable, etc., etc." is 100% BS when we know nothing at all about it at this time. Its OK to not think they're playable, its NOT ok to outright say they aren't when they haven't been deconfirmed in any way, shape, or form. Its still extremely odd that we've got a bunch of obscure DK trophies, but K. Rool and Dixie Kong are still missing.
EDIT: Ironically, although I've lost hope for my #1 most wanted character (K. Rool), my hope for Isaac has increased dramatically. There's literally no reason to cut him as an AT, there's no reason to cut any AT's, and although Wii U-exclusive AT's would make sense, Isaac does not make sense at all as a Wii U-exclusive AT.
