So, we have all 45 Sentai's Main Ranger Keys. Goranger/Gorenger through Zenkaiger.
With all of these Ranger Keys coming out, I would NOT be surprised if they rerelease the Gokaiger Mecha (including GokaiOh, GoZyuJin, and the Gokai Machines). Heck, maybe even some new forms for GokaiOh. It would be a HUGE waste of potential for them to just release the Ranger Keys and Mobilates and not give those who didn't get the Gokaiger Mecha to get them and release new Gokaiger Mecha to make it worth it for those who already have them.
Also, think about it. You can get the Mobilates, the Red Ranger Keys until Gokaiger, the Main Ranger Keys after Gokaiger, and the GokaiGalleon Key. Adding the Mecha would be kind of a minor budget addition.
