As HTC is using their own Sense UI, what happens when Android 2.0 is out? Or for that matter, 1.5.1? Are we likely to be able to upgrade and if so, will Sense be able to run on it? If it requires a new version of Sense, are HTC the sort of company who would make it available to existing users? It doesn't bode well that they aren't making Sense available for the Magic or G1, however, there could be legitimate technical reasons for this and I don't know HTC's history on the subject. Have they made upgrades available in the past?

Short version: is the cost of having Sense on the Hero that the device is locked to Android 1.5 and if not, what sort upgrades are HTC likely to offer?
