In these 2 links below you will notice that the Xbox 360 would have a 10 year lifespan. There have been rumors that it would come out in 2015, 2014, or even Christmas of 2013?

Here is where fallout 4 fits in. If the Xbox 720 comes out in 2014 or 2015 will we have to wait that long for another Fallout game? Bethesda will probably want that because the next Fallout will have better playing features, graphics, and more things to do in the game. But would everyone want that? There was a 2 year development period between Fallout 3 and New Vegas. It would make scence to release one in 2012. Games like Call of Duty Have a 1 year developing period between their games. Actually, we haven't heared anything about a Fallout 4 coming out in 2012 or else we would have heard about it by now and seen adverisments. Bethesda just made Skyrim in 2011. So they need a 2 years to make the game and announce it. They had the 2 years of developing and advertising with Fallout 3 and Skyrim. With the Xbox 720 coming out in Christmas 2013 or 2014 will we have to wait another year... or 2 more years or longer?
