Console or 3DS, It's hard to say which one looking at the sole image below. I'm going with 3DS, as it makes more sense after the DS game. What do you think?

Not sure, but I think I heard tell that this image could be a false leak. I certainly hope a sequel is in the works though, there's plenty of room for it, and this one was fantastic.

Kind of silly for a double post necro from so long ago, but it looks like there's a very real possibility of a sequel of some sorts (or at least a new game in the Little Tail Bronx world): http://www.n-europe.com/news/solatorobo-sequel-in-development.

That being said, I am definitely keeping my ears open for further developments!
