Halo 4 will be on xbox 360!

People have been skeptical all along whether or not halo 4 will be for xbox 360 or the anticipated 720! well the answer is now here, it will be released for the 360! With halo CE anniversary edition released today it was a perfect time for the announcement. 343's Frank O'Connor has confirmed that not only will it be on the 360 but it will also run off the old halo engine. On NeoGAF forums  he wrote
"Halo 4 will be on Xbox 360 and use a modified core of the Halo engine(s), Not really a singular engine since it goes through fairly radical evolutions all the time." Either way we are excited to see what is to come of halo 4!
