The Cyber Gundam link that Kiryu provided says they're TWE's, that Blue and Yellow are for January 2014, Kabuto and Kuwaga are for December 2013, and that preorders open on the 25th. At least that's what I got from it.

Yup pretty much. Sounds perfect to me :D

I find it odd that the Gouraigers are coming first though but they may have something to do with their Akibaranger appearance.

That's assuming Bluefin are able to get them in the first place (which I assume they will, but still). Otherwise there's no guarantee the price suddenly isn't going to skyrocket after release.

2-packs are fine as they are, any more I think is pushing it. 2-packs are a comfortable way of getting the figures out quickly, but at the same time acknowledging not everyone can afford a whole team at once.

these four plus Hurricane Red are on my purchase list for January :D.

Yes! This is awesome! Thanks for sharing this news! I hope Shurikenger is coming out soon!
