D&D Fourth Edition Books To Be Released in June
Bill Slavicsek, R&D director on Dungeons and Dragons at Wizards of the Coast, has announced via his personal column that the three core books for Fourth Edition will all be coming out in the same month. When the new game version was announced at Gen Con this year, the initial idea was that the books would be staggered over a three month period. "After conferring with our various trade partners, the Sales Team here at Wizards came back with word that they'd rather have the three core rulebooks release in the same month than over three consecutive months. As that's how we originally wanted to release them, Brand and R&D got together with our Production Team to see if we could accommodate the request. The answer is YES! The new release schedule looks like this: May: H1: Keep on the Shadowfell 4th Edition D&D adventure with Quick-Start Rules. June 6: 4th Edition Player's Handbook, Dungeon Master's Guide, and Monster Manual." As a note, the article is trapped behind an inane login for the Dungeons and Dragons Insider site. Hey WotC?

Really, 3rd Edition lasting from 2000-2008 with a revision in 2003 isn't all that much shorter than either of the previous editions.
