Are there any photos or layouts of the upgrade kits for the S1/S2, is it true the S2 could be upgraded to do 2Th/s?
That's the theory right now, but nothing has been released, AFAIK, other than the drawing in the OP.
I don't think S2 upgrades are that high on their priority list tbh, will be a month or two before they bother offering upgrades for them, simply doesn't make sense to upgrade the S2s yet.
