The only difference between gimmicks and innovations is that innovations are kept on the product and become a fundamental part of it. Gimmicks can go and few people will really miss them. Only time will tell what becomes innovation and what is labeled as a fad.

That's sometimes true but not always. Clear improvements to functionality, for example, such as the jump to 16-bit graphics, are regarded as innovations from the start.
Sometimes gimmicks are planned purely as gimmicks, with the developers well aware they are going down an evolutionary dead end. More common, as you said, are the occasions when the designers hope a gimmick becomes an innovation. However, the longer an industry exists, the harder true innovation becomes.
I don't think the D-pad was a gimmick, though, in that it was a move based on functionality rather than marketing strategy. A gimmick is a marketing focal point used to attract consumers. I could be wrong but I don't remember Nintendo advertising it in that way.
