-Sega- Releasing too many hardware in small amount of time.
-Nintendo- Staying with N64 cartridges (even back than that rely wasn't bad decision because every disk based console failed until PS1). Wii U revealing, marketing, naming, pricing, game pad, launch titles...bloody mess.
-Sony- PS3 $600 launch price, very complicated CPU. Vita, price, price of cards, 1st party content.
-MS- XB1, inital plans about DRM and block of used games, releasing console with higher price with less power than PS4.

Pretty much all of this.  Each of these points played a massive hit to each of the companies.
