The US dealers should have the brochure now. I got mine a month ago, so I don't know why they wouldn't be available nationwide by this point.It's crazy how I can find out anything I want to know about the CLA on the forum, but when I engage the dealership for info, they claim they have no e-brochures or anything!
Actually got my hands on a copy of the brochure. It has minimal info and doesn't show full details as a real brochure should. The car is three months away from hitting the showroom floors.
