the theory going around to why the vita failed was the the system was too powerful for its own good, not to mention the bullstuff propietary expensive memory cards you needed to play anything
Contrarily, I think the only reason the switch will succeed is because they have already heavily used IPs to smash out games for the system. Mario, Zelda, Pokemon, Splatoon, etc. along with new IPs like Arms that work well from the console side. Like what actually good IPs does sony have? I am positive the vita market was mostly JRPGs and other stuff you could get on a PS3/360. The top selling Vita game was god damn minecraft selling 2.27 million units. Even if we go down the list it's all stuff you can find on the ps3. there was no need for this. LittleBigPlanet? Assassin's Creed 3? Black ops? FFX? god damn, there's no actually worthwhile games!
