While I wasn't at Trainfest this year, seems like they had some trucks on display perhaps someone else has the info. Having used some of their trucks in both HO and 1:29 they are die cast metal fully sprung with braking gear present. Nice detailed for sure. I can't imagine they would do anything different for O scale, just a question of what they are types they are offering.
Really nothing present on their website that I can find regarding the future product(s). What I did find was a post on their FB site with the following photo of arch bar trucks, looks more like Bettendorf to me.
