Sega was likely going to release an "enhanced" controller like they did before with the 6 button on genesis and the 3d pad on Saturn, only with dual analog and 2 additional buttons. The protocol already accounted for it, and Quake 3 preemptively did make use of it.
The idea might have been to release it with a simple controller for simpler launch titles, then roll out the enhanced controller for more sophisticated ones down the line.
