Super scalar was really Sega's hallmark, it didn't really happen much on other machines anyway. It was super impressive back in the 80s, but by then the focus had switched to something influenced from Mario Bros and the likes. Also, when competitors started to provide very fast rendering on a bitmap (instead of raster rendering, line by line), it was when memory became faster and cheaper, and we were moving to 3D.
It's also not obvious to do on the Neo (I have still not understood how he skews sprites mid-frame, I thought you couldn't touch the sprite list in real time because the hardware did some form of prefetch and caching it for rendering ).
