Of course, given GM's track record of getting new tech 'right', it's likely just as well. Going back to the 50's (60 'vair, the Tempest rope driveshaft, the Buick AL V8, first couple of years of the FWD Toronado/Eldorado), the 70's (70 Vega), the 80's (X cars, THM 7004R and even the 200 trannies, the Olds Diesel), the 90's (the early Northstar engines and FWD trannies) and even in this decade (the SSR, first couple of years of Trailblazer DOHC 6). Folks that buy a GM model with significant 'brand spankin new' tech must like to have the dealer's service adviser as their best bud.
