On 4th June 2008, Sony cancelled both Eight Days and the ps3 'The Getaway' title. However, Jim Jagger who is (or was) Animation Director on Eight Days has released a demo reel including some examples of his work; and pre production footage of Eight Days features prominently.
Could this be a sign that Eight Days is back in development? Or confirmation that Sony have abandoned the title, leaving Jagger free to do what he wishes with his contributions to the game?

Polygon: "We look back at Sony London’s dropped PlayStation 3 buddy-themed action game."
So Sony cancelled Eight Days but didn't know that it was them who cancelled The Getaway 3
Getaway series should be brought back especially now that Sony has more diverse developers. Getaway 1-2 HD remakes by bluepoint

What went wrong for the co-op action title?
I thought It was well known that it was canceled because they felt it was competing with too many other cover based TPSs including their own Uncharted. Wish they would've brought it back, but by now I'm sure Londin Studios isn't interested in making it anymore.
The trailer was completely faked and they didn't have anything actually working according to a Eurogamer video

In this article, we try to list eight cancelled games that looked the most promising. Before we start, if you haven’t already, be sure to read this list over cancelled games, too.
Mega Man Legends 3 is the one cancelled game that sucked the most for me. Blaming it on the fans was a real jerkish move, too.
Promising? Maybe they sounded good, but, for instance, Redwood Falls and Shadow Realms never saw the light of day because they weren't anything exceptional. The tragic ones are the ones like Star Wars 1313, which was cancelled because of Disney's buyout of Star Wars, or Insane, which was cancelled because THQ was going out of business. I can only guess that Agent, Eight Days, and Starcraft Ghosts never made it anywhere because they didn't live up to expectations. Maybe they weren't any good, maybe they were too ambitious, maybe the tech at the time couldn't support them . . . we simply don't know.
I was once excited for the Pirates of the Caribbean game, Armada of the Damned, but chances are it was cancelled because it wasn't living up to expectations, so there's really no point in being letdown by it.
I hope it's back from the dead, look's awesome
Considering the leaked dev footage I at least hope that those assets are being put into another game.
apparently that idiot gamesblow just stated that its in the works. apparently talking about it on twitter. I sometimes doubt his credibility. he said hes finally opening his site this friday. he better not be joking this time.
While I do believe Eight Days is still alive, I doubt gamesblow know anymore than the rest of us
this and the getaway im holding my breath on this these being back on production
