This is an easy one. The first year of the C6, the old 4 spd auto was available. Rumor about a 6 spd auto was out there, but naturally GM wouldn't confirm or deny it. Duh, gee, ya think this could be happening all over again. If an 8 speed auto is planned for next year or the year after, ya think they're gonna tell us ? Would you if GM was your business & you're trying to sell C7's with an old school A6 ?

That's true, but they are not developing a trans for just the base c7. They have to design it for the planned output of the premium models. I would imagine that they would like to avoid a situation where the computer has to continually (and silently) reduce output to protect the driveline. Probably something the designers of that jag pig wouldn't be worried about.
And you do not know what horsepower and torque of the engines that GM is planning for the C7 in the future or what transmissions they will use.
Currently GM has a transmission that will handle the 580 HP ZL, so it stands to reason they will also have a 8 speed auto that will handle 580 Hp.
And it also stands to reason, that if Jag offers a 580 HP engine, that they to, will have a transmission capable of handling it.

The 8 speed automatic for both the trucks and the corvette are delayed because of bankruptcy.
The 6 speed automatic is probably holding back 2 mpg to the a8.
I believe the performance difference will be a tenth of a second
