This was before the Super Monkey Ball 3D release date in Japan was announced.YayMii said:Just because it might be a US launch title, doesn't mean it won't come out in Japan first. Don't forget that Japan's getting the 3DS before everyone else.Goli said:People should look at news post dates more often.Traverse96 said:So, it looks like Sega plans for Super Monkey Ball to be a launch title for the 3DS, perhaps it'll be a launch title in EU/US?

So it looks like the launch in other regions will be slightly different.

A japanese developed game that doesn't come out in Japan first. Somehow that doesn't make sense (save for when Nintendo does that, but we're talking about Sega here).
Same for your edit regarding DOA. I'm pretty sure Samurai Warriors will be a launch title outside of Japan too though, since localized screenshots were shown at E3.
At the time of the post I assumed it would be released later in 2011, now we now it's gonna be released on March 3 in Japan.
