You might want to look into the SilverStone RVZ01 when it comes out. It pretty much exactly fits the bill for what you are looking for.
I found a page linking to it, unfortunately it is not in English, but Google Translate does a decent job. (It is about 3/4ths down on the page)...
The only real reason that I want to get a console at this point is for arcade fighting games like the Street Fighter line. This is really only because I know I would be playing against people at higher ranks who are using an arcade stick vs a keyboard with macros.
