Dale told me this a while ago, but now I've got confirmation that I'm allowed to post the info:
*The dual driver model that people have mentioned is to be called the AS-2. It uses a 15mm driver and a 10mm driver, both dynamic (obviously).
*Just like with the AS-1 series, there will be a "universal" ASG-2 to go along with the genuine custom AS-2.
*The customs will have way more appearance options than the current models - metal, wood, or other premium faceplates, that sort of thing. Dale says the AS-1 series is their way of doing quality assurance on the manufacturing process, which is why they kept it simple with just the frosted clear shell.
*Dale did express concern about the time frame - he doesn't want HeadFiers impatiently holding out for the AS-2 models. Aurisonics is limiting the AS-2 to professional touring musicians for a while, in an effort to "field test" them, ensuring they have the same long-term performance as the AS-1. When pressed for public release dates, Dale mentioned May or June of this year, with the possibility of a debut at the InfoCOMM show in Vegas (mid June). I always just assume these types of things will take longer than anticipated, so I'd say the AS-2 series is a minimum of 4 months out, which could easily turn into 6 months or more. Meanwhile the AS-1 models are here right now, sounding great, and priced extremely competitively.
Unrelated to the AS-2, I'm still trying to nail down a good description of the sound for the AS-1b. The good news is that I'll be ready to send along the ASG-1 for people to try, maybe within the next week or two. I believe Average Joe will be first in line, but anyone else is welcome to be on the list (I haven't compiled anything official yet).
