Matrix Games announces Decisive Campaigns: The Blitzkrieg from Warsaw to Paris, a new World War II strategy game from the developers of Advanced Tactics: WWII. They say this is "the first in an innovative series of operational World War II wargames that also include a strategic element." A product section for the game offers details and screenshots, but no release date. Here's a bit more on what to expect from this: "The Blitzkrieg from Warsaw to Paris simulates Germany’s military successes in Poland and France in 1939 and 1940 (including also a hypothetical 'Sea Lion' invasion of Great Britain if you do well enough)."
