Going the remaster-heavy route is bittersweet for me for this reason. There will inevitably be games left in the dust that would've seen a rerelease under something like NSO. Games like Double Dash, Melee, and the Mario Sports titles will almost certainly stay behind, and the demand for titles like Kirby Air Ride and Baten Kaitos seems relatively small.
However, many of the games will be there eventually. If they're truly listening to fans, TTYD is a matter of time. IntSys was always going to get to Fire Emblem: Path of Radiance at some point without a nudge from Nintendo. Pikmin should show up. We already have Sunshine, and the more imminent rumors are promising.
