When I saw the news I had to check the calendar. I thought it was June, but it felt more like April Fool's Day.
I suppose whether or not it comes to PC (or Mac, too) will depend on how well it does on the initial platforms. Grim Fandango has always been rated critically very highly, although that didn't translate into high sales when first released. I guess we'll see if 16 years of hype leads to better results this time around. (And if they manage to get all those damned elevator doors working properly.)
