However, Vers 2.0 is going to support SATA, not sure on the extra IDE channels, Tony might like to comment.
I have no idea how the upgrades will be managed, but I would imagine that as a Vers 1.* owner you would get a discount for Vers 2.0 but I don't think or IMHO agree that it should be a free upgrade from Vers 1.* as its a completely new product.
My advice is buy NASlite+ USB vers 1.5 and have a play with the software, you'll probably get a discount for vers 2.0 and you'll be well clued up when it comes to setting up those 12 drives
Good luck
