South Sinai? I'd say it's still safe. North Sinai - mostly no-go. But I've been taking groups of scholars, trekkers, and meditators into the south Sinai mountains and desert for the past few years perfectly safely. It's a fantastic area well worth visiting, and I would say safer than Cairo, probably safer than Rocklands, and maybe even safer than Wadi Rum.
