House of the Dead 4 arcade board not X360 based

When some House of the Dead 4 details began to creep out, people were quick to state that the nice looking and bad voice acting game would be running off a board that used some Xbox 360 technology. That ain't the case states House of the Dead 4 makers Sega. Since Sega is now owned by arcade lovers Sammy, it is believed that since Sega made their we-aren't-using-Xbox360-tech statement, they are most likely using a lower-cost version of Sammy's Atomiswave arcade board. Lower-cost meaning more powerful cpus and a nice looking graphic engine.
