I am skeptical. If nostalgia has been proven to sell as evidenced by the New Super Mario Bros. Wii (remake of New Super Mario Bros. DS) and others, then why would a company not pursue at least one remake or two?
How do you explain sequels? Sequels just as much as remakes sell because of nostalgia over the gameplay of their predecessor. You could not have had the success of Modern Warfare 2 without Modern Warfare. Without Half-life, there would be no Half-life 2. Looking at it in this regard, you have to hold sequels to the same standard as remakes because they are based off a previous iteration and only add a few new features without doing a complete 360 on the fundamental gameplay.
Myself, I hold no bias against remakes or sequels. I take them for what they are. Games made to recapture the phenomenon of the original.
