I think in the future, the path for upgrades will continue. It's just a little early to see who and what will be involved in the upgrade business or even what the technology will be. But what I did see, is that it was too early to drop the ERR product without something else to jump to.
I think Scott succinctly states the salient point in this whole affair - the product shouldn't have been dropped until a replacement was available, as many others above have noted as well. It's wonderful that he's picking up the loose ball and is going to keep running with it.
