Hi Slapshot,
Well, I'm not completely clueless when it comes to software development. In my day job, I do automation testing for IBM WebSphere, so I do have some knowledge of it. That being said, I did not know that AH2 was a complete re-write, but I suspected as much due to the time it has taken.
As to your other points, I can't disagree with you.
I think the main point of mine that you missed was that I, speaking as a customer, would've preferred to see them continue to work towards completing the planeset in AH1, and only then start a new re-write of AH. If only for purely selfish reasons(more complete and balanced scenarios, etc), I was hoping that HTC would wait to complete the planeset before moving on to a new engine.
As far as AH2, I played around with a couple of the early betas, but I've decided to wait until it "ships" before I try it again. I'm married with young children, so my time is limited to begin with.
