I had the same concerns you do (this happened to me with another product: I bought it 3 weeks before it was superseded, even after I had asked, “Hey! Do you have a new version coming out? And was told, “No, no, no!), so about a month ago, I asked the question to support. I was told they don’t have any plans to release a new hardware version for at least the next 6 months (5 months now). I was told the only thing they have planned to come out is a 3G version (which I, at least, thought was the PE, but that doesn’t have 3G capability as far as I know).

I am comfortable, given how much work is going into the continued development of the EE, that we don’t have to worry about new hardware for a while. But who knows. I could be wrong.
