It very well may be overkill for more than a few applications, but if someone (say, oh...me) was wanting to upgrade from a 1v5 to a 2v7, I would almost think that this would be a worthwhile upgrade instead as both will be additional cost anyways. Plus, this way later on the floodgates will be wide open for additional modifications.

However, like you say, it is yet unconfirmed if the new stage 3 will work N/A.

Here's hopin'!
