[Morrison's] run begins with the revelation that the battle between humans and mutants is over; a gene in humans has activated, spelling the extinction of homo sapiens within the next 4 or 5 generations; mutants are poised to inherit the earth. Then, in a massive attack against the Magneto-run mutant haven of Genosha, 12 million mutants are killed, including the baddest mutant of them all, Magneto.(And yes, there are bigger spoilers to be had than what you just read.)
With this setup, the X-Men face the task of preparing for a world in which the old ways and enemies are gone, and they face new threats (chiefly in the form of Cassandra Nova, described as a being of pure emotional energy, and Sublime, mysterious leader of the "U-Men"). And while Charles Xavier's ideology seems to have won, he must face dissent from within his school, in the form of radical mutant separatists who invoke Magneto on their t-shirts, and the relationship of the X-Men to a media-saturated, post-modern world.
However, Morrison's changes reach beyond the plots to the very conventions of X-Men stories. The team uniforms have been changed from colorful spandex to black leather, adorned in several places with a characteristic "X." The idea here is to make the X-Men a brand, just like McDonald's golden arches or Nike's Swoosh, to work their way into the public consciousness . (Wolverine, whose costume used to consist of yellow spandex, says "suddenly I don't have to look like an idiot in broad daylight.")
Jean's whereabouts is rather complicated, but the short version is: she's dead, again. For the full story, I unreservedly reccomend picking up Grant Morrison's New X-Men run-- the entire thing is available in collected editions (paperback or hardcover, start here or here). If the retro stylings of Astonishing are more your bag, you may not like Morrison's radical interpretation of the X-Men, but it's truly worth picking up.
