Speaking as the owner of a TT car (see sig), I'd much rather be single.
TT's are complicated. It looks like Medusa is living under the hood with all of the vacuum lines, solenoids, check valves, etc... TT's generate incredible amounts of heat, which is further compounded by the RX-7's poor cooling system. Trying to solve a boost problem with TT's will keep you awake at night too.
Single turbos of today can produce power with minimal lag and not run out of breath at high rpm. TT's were a band-aid fix before turbo technology caught up.
I nearly crossed the MS6 off my list when I saw that Autoweek article saying it would be a TT I4. Thankfully, it's not.
