Retro Game Challenge 2 a US possibility?

Ironically, the day I write a story about how you should be buying the first game, we get more news that the sequel could be released in the US if they hit a certain sales goal. Here's the interview between Spencer, a writer for Siliconera and Ken Berry, Director of Publishing and Jun Iwasaki, President of Xseed games:

So about Retro Game Challenge 2…

KB: It looks very unlikely that we will localize and bring it.

We’ve gotten tons of e-mails from fans that say ‘thank you so much!’, ‘we love Retro Game Challenge’, ‘it’s my favorite DS game of all time’, but when you look at the sales numbers that actually picked it up and really being vocal about it, it’s pretty small compared to the other DS owners out there. The sales aren’t quite there to justify bringing the sequel.

JI: Fortunately, we got that title, but honestly it has not reached our expectations sales wise. It’s tough to bring the game over. If the sales of Game Center CX 1 (Retro Game Challenge) dramatically increase we will of course consider it. It’s up to you guys.

OK! Tell my readers how many more copies need to be sold.

KB: 20,000.

JI: 20,000 more? That’s too small. We need more than that.

KB: At least 20,000.

JI: We have to reach 100,000.

KB: OK, that’s a lot more.
