Now they stick with two settings and a lot of 'generic' material. More importantly, they've started moving back into adventurers because I think somewhere along the lines they realize that people simply can't afford to keep up with $100 of 'official' books a month.
But, even separating out the product lines, TSR produced lots more supplements in a short amount of time. If you were a fan of just Planescape or the Realms, let alone some of the core material, you were buying just as much or more.
WotC's 2005 releases were:
Complete Adventurer (2005)
Dungeon Master’s Guide II (2005)
Fantastic Locations: Fane of the Drow (2005)
Fantastic Locations: Hellspike Prison (2005)
Heroes of Battle (2005)
Heroes of Horror (2005)
Lords of Madness: The Book of Aberrations (2005)
Maelstrom (2005)
Magic of Incarnum (2005)
Races of the Wild (2005)
Sandstorm (2005)
Spell Compendium (2005)
Stormwrack (2005)
Weapons of Legacy (2005)
That's roughly one hard-bound release a month, not counting the two map/setting supplements. Of those, virtually ALL of them are options. Only the DMG II or the Complete Adventurer would be considered NEAR-core.

That's not including other material, Spellfire, Dragondice, novels, comics and games that aren't AD&D-based. And the previous year, they'd had two more settings on top of these.
