Honestly, there's been a lot of zombie and apocalyptic type games... but not many done right. This is either going to hit it out of the park, or be a failure because it's so-so like all the others.
If Davies isn't the lead, it's obvious he's probably back at lead level design. Not sure on how i feel about it, since level design was one of my issues with Enslaved adn somewhat in HS. Beautiful, artistic levels that ultimately were tiny little cages and "arenas". Once you started playing, you realized how boxed in your really were, which was a huge disappointment when you see a large, overgrown city all around.
Druckmann and Straley both worked on U2, but who knows how much. Amy Hennig has always, to me, seemed like the brains behind Uncharted. At least character and story wise.
Anyways, it's good news that ND has a 2nd team and now can pump out yearly games. Hopefully quality won't take a hit, but it shouldn't if they've structured their development cycles and teams correctly.
