I have nothing on my radar screen right now, either. I think the Sig 320 has the potential for being the next big thing, and the modular system allows for one to morph the gun into other guns. Sig also has a tendency to manufacture their own .22 LR conversion units, so I can imagine a conversion unit being offered in the future. (Not that I have been able to handle a 320 in these parts.)
