Es gibt mehrere Anzeichen dafür. Das wäre ein genialer Schachzug von Sony.
A silhouette of Crash Bandicoot appears in the launch day trailer for the PS4 released in November 2013. The image depicts Crash, with an arrow, pointing to a gold diamond, similar to the logo for Sony Computer Entertainment (i.e. Crash returning to Sony).
Also in November 2013, Kevin Pereira of DeathSquad podcast leaks info saying Sony is about to bring back one of their biggest exclusives. (Sony did bring back Uncharted at the launch event; could Crash have been put on the backburner for the VGAs at the last minute?)
Rumors of Crash Bandicoot on PS4 continue into late 2013, as a source with Naughty Dog ties says the game "is definitely in production" and if Sony has re-acquired the rights to the franchise, it would be "one of the biggest, and well kept, secrets in the industry."
In November 2013, new Crash Bandicoot game appears on Amazon France, known for listing games considerably early before their official announcement. The game appears to be a reboot of the series, and is listed as published by Sony and is exclusive to the PlayStation 4. The link is taken down shortly after publication. The incident, however, is suspected to be a hoax.
And now, today: the official Crash Bandicoot website is taken down, and all references to Crash Bandicoot are removed from Activision's website. An archived version of Activision's original site can be found here.
