at E3, Sony as recently as January 20th was still calling its PS3 Motion Controller, well, "Motion Controller" in its official communications with a footnote that the name was still tentative. Of course, we've heard whispers that it'll be called Arc -- and we're not alone. THQ boss Brian Farrell has either been reading the same sites as us or (more likely) is privy to some inside information. During an investor call, Farrell referred to the "PlayStation Arc motion controller" multiple times in both his prepared statements and in the Q&A round that followed. Remember, this is the same man who loose-lipped the Natal launch date well before Ballmer confirmed it for late 2010. Yeah, so PlayStation Arc it is.
