I get that, yeah, the same was done with the original DS (Mario 64 DS). But that's not to say the DS version of Mario 64 was rubbish. It had some new additions to it, and I enjoyed playing through it. It was the same game, really, but it didn't feel like it was. I haven't played Zelda DS so have no idea how it compares to the original.
Using Zelda is a guaranteed sell, I know, there is a hell of a lot of love for OoT just like there was Mario 64. But if they're not lazy remakes, I don't feel it matters. If it was a GoW style remake, it would be wrong.
& surely end of the lifespan would be now-ish. Remakes on all consoles came out a long time ago.. RE4, Halo, Okami, Prince of Persia etc

In my opinion nothings really pushing any boundaries right now, everything's just more of the same
