While the picture shows 7, and the magazine scan from Model Graphix February issue showed 3, I believe just one GN Drive is to be included, same goes for the container, but without any concrete confirmation from any website regarding the exact number, I'll say that that's just what I think, but I'm not entirely sure about it ^^;
January 28th release (tentative date), 3,780 Yen (inclusive of tax).

On the other hand, Soul of Chogokin GX-50 Combattler V released this month (19th) must be a great hit in the market ^^ - it's scheduled to be reissued in January. Fans who missed him this month will get to see him again next month. ^^
The price is 18,690 Yen (inclusive of tax).
