Cards are a higher-risk endeavor in the US than in Japan. Especially since arcades are pretty much dead over here, so it would be nearly impossible to localize the entire Dice-Oh system.
If they release a card reader that goes alone with the game, maybe, but I believe Dice-Oh is designed mostly to be head-to-head. For the US market, people would want online, but generally parents don't want kids playing each other in online games... I don't know, it seems like something that ultimately wouldn't be worth the effort.
1) Lots of original footage to compensate for cutting all the very Japanesey stuff out.
2) Spring for a season that isn't set in Anytown, USA.
If the rumors about budget issues are true surrounding RPM, that probably rules out 1. And 2... well.. It's always going to be Anytown, USA. Despite not being filmed in the US, shot with US actors, and is co-funded by Jetix Europe. Oy.
I would have it called "Power Rangers - Back To Action" for the title.
The Story would take place in 2013, an asteroid has crash landed on earth releasing aliens that can absorb and use the bodies of humans. Mysteriously an Alpha series Robot is activated. Alpha recruits Four college students to help deal with secret invasion. With the help of a Quantum Physics student Alpha sets his plan in motion to retrieve Zordon from the past. Something goes wrong, and an inexperienced teen Zordon is transported to the future. A mysterious voice alerts the team to their Morphers , in which they become Power Rangers.
