Without Sony? Nah.
Okay, we'd lose a couple of good franchises (Uncharted and TLOU, mostly) but Sony are known more for their strong third-party support than for great games they develop themselves. Most of those developers would just be making games for the Wii U or Xbox One instead. Given how negative the reaction was to XO when it was unveiled, Wii U would probably have got a lot of the good publicity that Sony got.
If Nintendo were gone, on the other hand... they have a huge range of IPs that have been extremely well-regarded and influential over the years. Imagine a world with no Mario or Mario Kart, no Zelda, no Metroid, no Pokémon, no Animal Crossing, no Fire Emblem or Xenoblade or Smash...
