I'm of multiple minds. As a fan of retro animation, I love TAS as it is, quirks and all.
But as a realist, I know that (even compared to the modern flash animated shows), it still looks dated and that a CGI re-do using the original audio could possibly be a boon for syndication possibilities. Though the small number of episodes would also work against that.
What would I really want? In my wildest dreams? New episodes, animated exactly the same way, warts and all.
