Hopefully. The anime ended in 1997. Let it stay dead
I agree with this sentiment in general, largely because it seems clear Takeuchi has no desire to either expand the series or to give the reins to someone who will expand it. Crystal was a chance to expand the series beyond the old anime, but in that sense it failed so far.
What's sad is this franchise could have gotten more life if it had been willing to change. Time has marched on to the point where a lot of the elements defended as being progressive or revolutionary are downright problematic or outdated, while some of the themes of identity were never fully explored. With a similar universe but a new storyline, there would be potential for a new series that would marry the characterization of the old anime with elements of the manga and other continuities, but that would require work.
Sailor Moon is an enduring classic, and like so many other enduring classics, I'm sure it will continue to get new adaptations over the years. I think a new anime is a distinct possibility, but not for at least another 10 years after Crystal/Eternal finally wraps up, and ideally by a different studio though we may have to just accept Toei will always been involved. I also think there's a 50:50 chance of the next anime adaptation being a CG animated series.
Sailor Moon could be an enduring classic, but the franchise is literally stuck in the 1990s. It's a sad state of affairs when
Scooby Doo of all things managed to update with the times much more easily than Sailor Moon has.
I'm not sure what the deal between Sailor Moon as a property and Toei is, but I don't see any other studio entering the picture at this point.
The reason why I don't think there will be a new anime is because there is no new material. Once Crystal is done, there will be a relatively manga faithful adaptation. The old iconic anime will also exist. There won't be any need to retell the story.
I'll admit I'd love a 3D series with a new storyline, but I don't hold much hope because a 3D
series would
require redesigns of the characters, and there is no way Takeuchi will ever sign off on that.
