The gattai robo of Tenso Sentai Goseiger is revealed. It's called Great Gosei.
You can see those pegs on the wings, upper arms, and knees - I count all 8 of them from the picture above. But as shown at the bottom left of the image, there are a total of 14 spots for parts to be swapped and connected onto them. So it seems like Great Gosei is going to follow the "add-on-and-on-and-on"-type of design from the Super Sentai series since a few seasons back. ^^;
And no kidding on that. ^^;
The henshin device I think
