Sierra Entertainment has issued this press release, officially announcing the development of Empire Earth III which will be released this fall. Screenshots can be found here.

PC Gamer UK has posted an Empire Earth 3 preview, revealing that Mad Doc Software is indeed working on a new installment in this strategy game series. The game looks to be a bit more streamlined and focused, while offering a new campaign structure which is described as being somewhat like the one found in the Total War series. Four screenshots are included with the article.

The actual real-time strategy is also a considerable departure. While still based on historical fact, a broader, more exaggerated look prevails, much like you'd expect if Blizzard designed an historical RTS. And rather than the many civilisations previous games simulated shallowly, EE3's three generalised ones - western, middle-eastern and far-eastern - each have far more unique unit progressions and specialised hero types. [...] At this stage, everything seems more alive than in previous games. In the wake of the huge leaps forward made by Company of Heroes and Supreme Commander, this is exactly the kind of revitalisation to keep Empire Earth relevant in the modern age.
