I'm not sure what to think.
On one hand there is just so many 1950s to 1980s cool toys that could be played with in a fictional WWIII battle. It would breath some fresh air into a stale tactical subject (Ie Tiger = pwnage f0r evAr)!
But on the other, I can see that there still is lots of WWII subjects to cover. The Civil war in Spain, a true Winter war setting, the eary war Blitzkrieg in Poland and France, and the early and late war Russo-Japanese border skirmishes. Not to mention the Pacific and China/Burma.
It seems like only in the last few years that main stream game makers have figured out "Hey, there was an East front too!"
