Total War Going Back to Basics?

A new Total War game will be announced at E3 and rumours suggest the series could be going back to basics.

According to VE3D:

Though in possession of full details, our lives wouldn't be worth living if we divulged what we know, but let's just say that the new PC-only game eschews the gunpowder weaponry of recent Total War titles and gets back to basics.

I'm not surprised. Total War has become too big for Creative Assembly to control. Each more complex release has shown major failings in the AI. Many fans of the series have had enough - so perhaps CA is starting all over again with the hope of getting the AI right.
