I find myself unable to answer this poll, because I don't have enough information about what a "revitalized" AD&D would look like.
Specifically, would it be more in the vein of the "toolbox" approach we have today, just with AD&D mechanics? Or would it be like how it was in 2E, with a holistic meta-setting, including strong support for various campaign worlds?
The former wouldn't interest me much at all. The latter, however, would strongly entice me.
Back in the days of 2E (which was when I got into the game), it was what I now consider to be the golden age of fluff. Worlds were richly developed, and there were multiple plot threads running throughout sourcebooks, adventures, and even novels, making the various campaigns a wonderfully detailed place to play. I loved following the intricacies of various characters, or noting cross-world things from various settings (particularly in Spelljammer and Planescape, which touched other campaigns by their very nature). I liked the mechanics okay, but it was this fluff that enthralled me.
Then, 3E happened, and things got reversed. Now the various campaign worlds were largely treated in a hands-off style, whereas mechanics were front and center. I didn't like it, but adapted, and now enjoy toggling with the crunch of things first and foremost, simply because there's not that much else to look at compared to how it used to be.
If the 2E style of campaign world-development came back, then yes, I'd take up AD&D again. Otherwise, no.
