Sure, though that wasn't player perception at the time - that was a much more literalistic "this will be the last edition of D&D" thought.
But I doubt many of the new players were even around when the evergreen comment was made, or would be surprised to see a new edition (I doubt it'll be themed a la Catan or the like btw, that would potentially limit sales).
Board games are bad model, I'd suggest. MtG is closer, but D&D is its own thing and assuming it will function identically to another market/product will only lead to tears.
