Not sure, but it'll probably remain a secret until June 6th.
Maybe. But there are a lot of resourceful members of these forums. If someone can just find out who to contact, someone will probably do it. We had people calling the United States Copyright Office back before Skyrim's announcement inquiring about Bethesda's trademark of the Skyrim brand. I hear they were fairly helpful.
And sometimes Twitter is good enough. Never used it myself though, but it's a good medium for asking Pete Hines questions.
Project cafe?
I haven't heard on any of these.
Project Cafe is the code name for Nintendo's next console. It will be unveiled at E3 this year. Because Nintendo must always have the first foot in the door for generation 8 it seems.
