Found a thread over at RCUniverse on this one:

There is a quote from someone who said he contacted Castle and they give him this information:
"Alright this is what I got
It will be coming out in no longer than a year. He said about 6 months but didn't want give me wrong date.
Will be using Neu motor techniques. With a 2.3mm shaft option
Has max 35A.
Will come out after the monster max system."
Now the Sidewinder (maybe just a renamed Mamba25) information on Castles website says that it is a big jump up in power handling from the Mamba25 and they don't give a continuous Amp rating, but they say more than you can handle. To say the Mamba Micro Pro can handle 35A cont. doesn't really impress me too much......
Personally, I would get the controller because I like the placement possibilities due to the design much better than the flat shrinkwrapped Mamba25.
