Activision annoyingly got the rights to Crash AND Spyro. How it went was as follows.

Sony never owned the rights to either characters. Universal Interactive Studios always owned the rights to the characters, Naughty Dog and Insomniac signed on to make 3 games each exclusively for Playstation console. Whilst the contract ended after that, Naughty Dog made Crash 3 and Crash Team Racing at the same time, and whichever one got finished first would be published, that was Crash 3, but they got far enough in production of Team Racing to finish it off and that was the farewell for both of the original developers. That’s when stuff got bad. Crash did moderately ok, Crash Bash is alright. Wrath of Cortex however got plagued with development issues, the original game was going to be a Free-Roaming title. But a fall-out happened between Sony and Universal (Which was bought out by Vivendi and became known as Vivendi Universal) and that entire game was scrapped and they had to make a more standard crash game in under 12 months. Vivendi Held the rights to Crash, Sony kept the distribution rights to the original games. Poor Spyro though… Enter the Dragonfly… you know how bad Sonic 2006 was? Yeah, this game was WORSE than that, much, much worse than that. Mainly due to an even worse case of Winter Rush. It’s developers made that one game and were never seen again. Despite some moderately good games after that, the damage was already done. So Reboots where made. Which lead to the Crash Mutants series and the Legend of Spyro series. However, a merger happened between Vivendi and Activision, becoming Vivendi Blizzard in 2007. Spyro has since been used only to advertise the Skylanders series of games, and Crash has barely had anything for 5 years except for some cheap Ios games, and 2 cancelled games in 2010. Which were cancelled by Activision.

Anyway, I would want to see them in the game too, I bet Activision would ask for half the games profits just to let them in the game.
