The main problem with Beatmania in the US is that they don't advertise it enough. Most people have at least seen or heard of DDR, but to know about Beatmania you have to know someone that plays it. And they have to actually show it to you and explain it. With this new Rock Revolution thing coming out this year, you'd think they'd try pushing IIDX in the US along with it. I wouldn't even be surprised if they didn't push it because it doesn't have the word "Revolution" in its name. Even then that's a stupid excuse, because they could have just re-named beatmania with Revolution somewhere in the title for the US only or something silly like that. Whatever. I'm perfectly happy supporting Konami by buying the Japanese games. Perhaps websites that sell import games should tell Konami how many people actually import them, maybe that'd show them we're interested. Making a decision that there aren't enough people/arcade owners interested (the case with GOLD US I believe) is not a good idea when only a select few have even heard of the game. It's one of those catch-22 whatsits. We just can't win with Konami US, it would seem.
On the controller thing, theoretically Konami could make another beatmania IIDX controller with like ONE new improvement or feature or something to differentiate it from the old ones. Then people would be interested in buying the controllers, and they could sell them as a bundle again to sell the game too. Beatmania III would be nice, since the US controllers had a port for the foot pedal. Why make it if you're not going to use it? Heck, they could even just sell the foot pedal + game package, and another bundle of the game, controller and foot pedal. They could make profit off of the hardware if not the software as well. Japanese people would probably import it just for Beatmania III! Of course that's just moving backwards with the series, because of the whole 5 key thing. 7 key + foot pedal would be cool though, beatmania IV perhaps? or beatmania IIIDX? hahaha. I'm just brainstorming. It goes to show that Konami had a lot of options, and the one they picked was to do absolutely nothing, leaving us unsatisfied. Blech.
