They have not released any official information yet. The rumor is there will be two models one Super Blue (same as AI Sol) and a Color model (the one in the video).

I expect both models will be the same price. However this is just a rumor. They will not release any information.

Is it also true that the Vega cannot control the sols?
Reason I ask is because I wouldn't mind combining the two fixtures together but would rather just have one controller. I guess when they release it we may have an answer!

Thats a good question. I know there is a Sol "add-on" coming out at the same time to make the Sols wireless so perhaps they will be able to talk to each other.

that would be ideal I would love to test drive some vegas but dont have a big enough tank to justify it right now :P

That'd be nice to be control my AI SOLs wirelessly!!
