Sprint and the waiting game

[mconig78]

Here is my dilema I really like the Hero and I am getting tired of my Diamond. But it seems like everytime I buy a new phone a newer better one comes out a few months later. It happened to me with the Vogue and then I had to wait till I had some type of discount to get the Diamond. Now I have my full discount but I dont want to get the Hero if a newer better Android phone will come out. I know HTC has the leaked 2010 lineup but who knows if and when Sprint will ever get any of those phones. I read somewhere that the Google phone is working on GSM/CDMA multiple chip so it will work on both networks?? Is that even possible?
