As i posted in their company forum, I am not even convinced they have a prototype yet, let alone any active beta testing. All we have seen is the photoshopped pictures on the one page flyer when they anounced the Atlas series. Acurite refuses to answer any questions that are asked about the status of the Atlas. Even if they are into beta testing and close to a release of the product, it is a poor way to launch a new product ... announced at CES in January to get everyone excited about it, then refused to give any further information for more than 9 months now.
CES is a trade show. It's not so much about getting the end consumer excited. It's about building business relationships and getting products in the distribution channels. It's a safe bet that information is being transferred behind closed doors with potential business partners. End consumers likely won't hear much about such things unless someone generates a press release.
Acurite customer support reps aren't going to tell you much, if anything, than what has already been put forth in the spec sheets.
Testers aren't likely to say anything, either, unless they have permission to do so.
Beta testing is typically a short last stage of testing before a product release. The bulk of testing occurs during the development stage, which can last years.
Release dates are, by nature, subject to change. The CES press release said "later this year". There's still time left for Acurite make that. Take any other date tossed out with a grain of salt. Unless you have a formal contractual agreement for a specific delivery date, you don't have much to squawk about.
