Blizzard Developers show they are actually quite out of touch with how most guilds progress in raid content. Yes, the current glory of the raiders I'm sure are just going to go full throddle into Ulduar, but I think most of their customers who raid are likely going to maintain split time between Ulduar and Naxxramas for a bit longer. Having a goal of appreciable value (IE, more than just points or requiring flipping through a bunch of subtabs) related to those achievements continue would still give people something to spice those trips up with. I mean, in BC I basically ran Kara for over a year even while we were doing a lot of other raids. I at least had Attumen's mount to test fate for, but Naxxramas doesn't even provide that now. Still it's very likely most guilds have an influx of people to gear up in the lower tier, or got a slightly later start and will wind up doing a boss or two in Ulduar while finishing getting people set with Naxx.
I think it's out of the habit of most guilds to just fully push through new dungeons, so expecting Ulduar to just fully replace Naxx for everyone is to deny the way most of the guilds and their players operate.
