I just got a newsletter from some German RPG Maker site I didn't know I was subscribed to, which mentioned news about the so called "Action Game Maker" by Enterbrain, the minds behind the RPG Maker (or at least the guys who bought it, from what I recall).
I can sadly only really link to the German post the newsletter linked to but it has some nice screenshots:
http://rpga.info/forum/showthread.php?t=47445It has also more extensive information you can't decipher than the original product page, so yeh.
In essence, it's like a more customizable version of RPGMaker VX built around the concept of Action Games (Jump n Runs, Shooters).
What personally peaked most of interest though was the export option. Apparently the maker is able to export your game to a Standard exe with DirectX, Microsoft XNA or Adobe Flex SDK, meaning, if the information is not wrong and I understood it right, that you can export your game to Windows, Xbox360 and Flash.
I ran a forum search before posting this, which didn't turn up anything, so sorry if this is already widely available information.
If I judge the Japanese homepage right it's due for a (japanese) release on 5th March.
Edit:
Almost forgot, in the same Newsletter they also mentioned that Enterbrain released Demo games demonstrating the makers capabilities.

Although I think that wouldn't have been so hard to figure out either, but eh.
