Was it....
1)The fact it was only offered through the Lionel Store?
2)The issues with some of the gearing on their current offerings?
3)Many people still don’t know what a Class K is?

I spoke with Scott Mann at York about this. He said "he wished that Lionel had spoken to him first". I think your answer is:
4) 3rd Rail already did the K2a, and they're still available; for a fraction of what Lionel was asking for their hybrid.
I have a 3rd rail model and it is excellent. Not saying that the Lionel would not have been great. But only a N&W wonk will recognize that the K2a is different than a J. It's a 4-8-2, with a riveted tender, air pumps shrouded on the fireman's side, and scale 6' shorter than a J. But it's got the bullet nose and Tuscan / Gold stripe just like a J. None survived. And the J's have been offered extensively, by almost everyone. Everyone knows the 611.
I would challenge Lionel to offer a hybrid of one of the MANY never-offered N&W prototypes. A few could be S1a, K1, Z1a and b, W2. I'd be a buyer for all the above.
