That's one place viral advertising could lead to a nasty infection.
www.torusgames.com no sales figures, but I've work most of the titles we've shipped in the last 10 years. They're all console and hand held titles.
If the game is developed with localization in mind during production, there's no reason the localized version cant ship at almost the same date as the English. I've shipped ~20 games that have been localized and the EFIGS (English, French, Italian, German, Spanish) version has never been more than about 1 month after the English release.
