OH. MY. GOD.
Actually, I don't know how I feel about this. On the one hand, it should have happened years ago (or at least a cartoon series). On the flipside... it's finally happening, and a galaxy-trotting Ratchet film would be just PERFECT.
From that teaser, actually, it kind of films like whoever is making this definitely captured the essence of the humour in Ratchet, which is absolutely great. I believe it's being written by someone from Insomniac too, so yeah, fantastic.
And the best thing I can draw from this is that Sony have future plans for Ratchet. After the last two shaky entries I wasn't too sure what'd happen with my favourite space-travelling Lombax and his robot sidekick, but now I feel much more reassured. Ratchet PS4 incoming (and hopefully HD Collection, too).
P.S. Side note, but hurry up and make a Sly Cooper cartoon series, Sony. I finally feel like they're getting this stuff in check (Invizimals is getting a TV series too); so why ignore Sly? =/
