Was at Costco today and asked if any new models coming out. They said Rexton is coming out with a rechargeable model, which I'm guessing is based off of the new Rexton Stellar model which is similar to Signia's Cellion Primax. All speculation, but it did seem like this model will be out soon. Also asked about Bernafon and they said it hadn't been released yet.
Also bought batteries and the package said "Now with easy to use packaging" and it was indeed much easier to use than their old packages.
