Could the GOW Multiplayer Beta hinting at what to expect from the single player campaign?

[M.U.G.E.N]

So I have been thinking. The beta is basically split into two sets of warriors, spartans vs Trojans. This got me thinking what if, the battle of Troy was a huge part of the single player campaign? 

They are also offering pre order bonuses in the form of popular greek heroes such as Achilles. 

So either the battle of troy is the angle they are using on the multiplayer OR it's part of the single player campaign. WOuldn't it be just fantastic if they do use it in the SP? So much potential. All the famous warriors, and greek gods fighting it out. 

By the way remind me if they have used the battle in a previous gow title as I do not recall it happening yet.
