Deep Down trademarked in North America and Europe
Sure, it's not that surprising that Capcom would be looking to expand Deep Down to the international audience especially when it was shown on stage during Sony's PS4 reveal event, but they still have yet to announce a date for the West despite talk of an open beta arriving in Japan sometime around the system's launch in late February.
Recently, DualShockers unearthed a recent trademark in the US database and the European Union. It would be very surprising if we don't hear anything by the time E3 rolls around later this year.
