Not sure how I feel about this.
On the plus side, SHANE F*CKING BLACK. With him writing and directing, it's sure to at least have something going for it. Based on his input at least I'll be going to see it. Hopefully his involvement might help it get the R rating it deserves, too, seeing as that's his pedigree (Iron Man 3 notwithstanding).
But I dunno if I like the idea of the film being a reboot. It's not like there's an overly invasive level of backstory that they need to wipe clean to make a new film work. It can quite easily be an unconnected sequel. I'd far prefer that.
As a slight aside - seriously, why do people keep claiming Predators was a reboot? It wasn't. It specifically mentions the events of the first film in dialogue. It was a sequel.
