I look at it this way....deciding whether or not to root your phone is a lot like deciding whether or not you should buy a gun. Its better to have it and not need it then need it and not have it. Besides, whatever Samsung releases will pale in comparison to what the devs are going to do with it, so if you want to maximize the performance of your Epic you'll have to be rooted anyways. And, of course if it ever becomes a problem, you can always use Odin to flash it back to stock. I've done it several times already, its pretty easy.
