Last I had read, Singer was no longer involved with a 'Logan's Run' remake, but instead 'Drive' director Nicolas Refn was going to do it with Ryan Gosling. Although that's gone a bit quiet as well.
Then again so has Battlestar as far as I know.
Topically, you can't do it as camp and silly as the 70's version and no two hour movie could hope to even scratch the surface of the themes and subject matter that the reboot did properly. So, another version would seem to be stuck in no man's land where it would have to land somewhere between the two.
A complete 'third' reboot skipping both prior versions would seem best. The 70's version is too old and reboot completed it's story from start to finish.
