Most games that actually get released in the west at least get confirmed for a western release before their japanese launch.
I 'm confident this game will come anyway, but not having any info on a western release 2 months before the release of the Wii version in Japan IS concerning.
The time to support the localisation of a game you want is NOT multiple months after the japanese release. That's way too late.
There's no news on DQM:TW either and it's been out for almost 2 months. Nintendo/SE are getting really lazy about their localizations. --- I am not an early adopter. If your system is as awesome as you say it is, it will still be in stores when the games I want are out.
