Yes, I take your point. If the product was advertised as being compatible with the upcoming wireless system then I can see some users, including yourself, will have bought them on that basis. I think there is worth in developing the idea further though, which may mean introducing a new product in addition to the upcoming add on. That is the way of development and I don't think Sleek should worry about alienating existing users of a former system. Personally speaking I would be more inclined to spend money on a totally new product with enhanced operational functionality (for me at least) even though I already own the SA6s. Don't get me wrong, I'm certainly not knocking the product (hell, it's not even released yet) and it's good Sleek are forward thinking enough to care about developing their products.
