Just to clarify...
As discussed in other threads, WotC has announced releases through early 2008, and they are pretty limited and "rules light". They have practically no player oriented books and Rules Compendium is the only one I would describe as "general interest". There is not a PHB II, DMG II, spell compendium, or even Book of Nine Swords or Magic of Incarnum in sight.
Hence the question. Are they just winding down, releasing a new edition, moving content online, taking a break, or something else?
