Doubt it, the purple shading on the planet reminds me of the endings in Playstation All-Stars Battle Royale, this is just speculation now, but the Thugs-4-Less mention by Insomniac may have been an hint for a stage in a possible Playstation All-Stars Battle Royale 2. BUT in the chance the poster IS R&C related, It certainly wouldn't be a J&D crossover, I mean, when was the last time we had a Jak and Daxter game? Not only that, but the fact that R&C is now a series that seems to mainly target towards kids, the world of Jak and Daxter would just loose it's charm, everyone would act out of character and probably be all chibi thanks to Ratchet and Clank's new art style, the crossover would loose it's meaning. Unless the almighty and powerful Naughty Dog is the brain behind this crossover. After all, they just released The Last of Us so they have the whole crew together now, and what better way to revive a franchise than to make a crossover with it's biggest rival.
