I would say the frequency of new packs being released has died down, but I doubt the actual work has. If it has, though, it's more likely lack of time, seeing as this is a busy period for most students. There were definately a large number of new projects when high-resolution texture modding was 'invented,' but I never really believed that most of them would get far, save the must-do N64 games (this would be, I guess, the Zeldas, Marios, SSB and certain wrestling games). It's clear that the community has shifted its attention onto these 'big names,' but only time will tell what happens after this.
