While it's been listed on the Release Dates page for a little while now, Capcom of Japan recently added the third installment in the Rockman EXE series (known as Megaman Battle Network in North America) to their upcoming games page.
Nothing really is known about the title, but knowing Capcom, and the series, it's likely to play like the first two games, though with new features, battle chips, etc. Meanwhile, US gamers are still waiting on the second game in the series (appropriately named Megaman Battle Network 2) to be released, which should be around the middle of next week.
In related Megaman news, for those interested, the Super Famicom game sometimes referred to as Mega Man 9, Rockman & Forte is also now listed to be released on the Game Boy Advance.
There's no word on a domestic release on either title, but they're both pretty much a sure thing.
