There were no guilds that raided Naxx to gear up for Ulduar with the ultimate goal of clearing ToC. You could take a fresh 80, run a few heroics, then step right in to the expansion's third raid tier, never having seen the previous two tiers. They effectively made their existing content 100% obsolete.
It baffles me that Blizzard argues that they don't have infinite resources to pump out raid content as fast as it's being consumed, but then each patch they actively destroy their precious raid content by replacing it with valor gear.
