This isn't completely shocking, since Morrison claimed to be working on the big crossover event for 2008, but it's been confirmed at San Diego.
GRANT MORRISON IS WRITING FINAL CRISIS.
Yes. That is very good news. Not just because that means I can look forward to a good story, but because Morrison isn't going to use the event to get rid of the multiverse (which he obviously adores) or add a dose of "realism" (which he hates).
Here's what we can expect: a fun, cosmic, apocalyptic, symbolic Silver Age-style imaginative romp, maybe with more than a bit of the Kirbyesque.
Here's what we can be safe NOT to expect: Superman crying, heroes slowly dying of cancer, pointless rape, governmental registration of super-heroes, bad dialogue, everyone turning out to be a Manhunter, neon green ink, stupidity.
I'm sure Morrison will have some things to say, at least some hints, this weekend, but for now, at least we can read what artist J. G. Jones has to say: Final Crisis should be good.
UPDATED TO ADD: This comes from Newsarama: "Morrison said it would have Anthro the First Boy on the first page, and Kamandi the Last Boy on the last page." Yeah, that sounds like a suitably epic time span. And, Kamandi!
