you linked a wiki to prove that it exists, which linked an old news article that got it's information from the same source I did and didn't even know that Galaxy 2 was coming out before E3 (at the time). The source you linked is no better than me making up whatever I want. However I do have the investor relations notes, and it was never stated that Galaxy 2 would be at E3. If anything you should be trying to prove that it will be at E3 with a reliable source.

EDIT: I did some more digging, and every single one goes back to the same wrong source, which points back to Nintendo's own website, which doesn't claim to have Galaxy 2 at E3.

There's no doubt it'll be at E3, but probably not in an extraordinary fashion. Nintendo always showcase their latest releases at E3 and say "We've just released these awesome games, and we still have more coming!".

Wrong info is wrong info.
