While it is in the online catalog, I would have to agree that even a small blurb with the Big Boys would have been appropriate. Something like "for more on the Base3 check out the online catalog at www.lionel.com" .
As far as availability, Lionel is a small player in the electronics world. This could potentially put them at the rear of the production schedule and I suspect parts being as they are isn't helping. Dave was also still working out some thing per his Demo with Dave updates. It will get here soon enough.
