I'm a bit surprised the brother are not paired together, but I'm sure Wayne has his reasons.
I read yesterday that Shark has not finalized his program and might not even be in GTP next year:

My guess is Honda is still upset with the Rolex tire pressure snafu, and this gives them a chance to consolidate their program under one team.
Shank will end up with something. Again, just guessing, but Cadillac has stepped up before and that's probably his best bet if Acura doesn't work out. I kind of doubt BMW will entertain the idea because their program is just starting to come around, and they will have to supply their WEC program next year too. Porsche is supposedly tapped out on production. Maybe Lamborghini is an outside hope. It would be a real shame if IMSA can't keep a championship team like Shank in the lineup.
But if no one steps up and provides a car for them, that kind of underlines my point that manufacturers should be required to sell X amount of customer cars.
The part that does not make sense is to me is Dallara, Ligier, Oreca and Muttlymatic are all in business to sell cars. For a major auto maker, another engine or two shouldn't be a big deal. Everybody would make money and we would have more good cars. Porsche has always understood the strength in numbers approach, and even when they were a small company, they still cranked out the cars. They built over 100 of the 956/962, but GM and BMW can't match that?
I can't believe that GM or BMW would struggle to make more engines, and I can't believe the chassis makers wouldn't like to sell more cars.
Then again, I might just be too greedy.
