Uncharted perfected the formula of an "Indiana Jones" type game. If they follow Uncharted, they will be replicating the "perfect formula", but it will be just a copy of Uncharted. And Machine Games cannot match Naughty Dog. So it'll be a "cheaper" copy (for the lack of a better word).
I would be pretty disappointed if Indy will be shallow game with focus on style over substance. I get why many people like Uncharted games, but honestly I prefer more reliance towards varied gameplay systems.
But if they will be able to keep storytelling style of Wolfenstein games in Indy, that would be instant upgrade over Uncharted in my books.
