The US release of Maximum Tune 5 is actually 5DX+.
Namco only eliminated the "DX+" part of the logo from US builds to avoid confusing players not familiar with the Asia-only 5 and 5DX.- Actually I'm dumb, it's jossed. It's just vanilla 5.
When/If Namco releases Maximum Tune 6, it will be applied to all regions.
Though, I'm not sure how jumping Americans' play data straight from Maximum Tune 5 to 6, skipping 5DX and 5DX+, will work.- As much as it kills me to say it, the chances of us NA folks ever getting our hands on any version of MT 6 are slim to none. It's more than obvious that the game isn't nearly as popular here as it is overseas, especially now that we're a full 3 versions behind ANZA (though somehow we're ahead of China). Bamco already forced us to start over from scratch with the jump from 3DX+ to 5 in 2017. Unless there's a very strong showing of support (and believe me, I've done my part), it'll likely happen again from 5DX+ to 7, whenever that comes out.
Western and Eastern Version
It is possible that Maximum Tune in the US will be a completely behind the Japanese(, Indonesian )and Asian version of the game and contnue without Wangan Midnight title and if the game finally has a European version, it will be the same version as the US one.- I hope it doesn't continue like that though. Please merge all servers and make Maximum Tune a worldwide game >_<
