I think with a single carb design on any inline intake, your going to always have a possible fuel distribution worry. I can see a market for a 2 x 1 intake, but don't know if people will look for it as a worthy everyday driver kind of bolt on or if they may feel having to deal with getting/keeping 2 carbs in sync is more of a hot rod setup and miss the appeal to the target crowd the single 2 BBL intake will attract.
I can always make both intakes and not settle for just one or the other....that way you get product availability for both markets. I think in the past with so few options in the intake category, many inline guys have had to settle or compromise on intake choices and not had one that entirely filled their needs 100%, such as installing a 4 BBL when a 2BBL would have been fine, etc....
