Sorry I'm late. Been too busy to pop in here.
(No, not having any trouble with the thread, but I'm also a staffer, so... I don't know if that would affect anything.)
It makes sense that the new studio is looking to do something different. I think it could cause something of a hassle if they tried to imitate the previous films' looks. Though, honestly, it's not like Cair Paravel would have to look the way it did in LWW anyway, what with the ruins in PC and then Caspian's rebuilding. The design could very easily be different because of that one fact. Plus, SC explores territories outside of Narnia, so even if anyone is tempted to connect SC with the three previous films, it will still make sense to have all-new designs for the Giants and Underworld 'cause we've never seen them before.
I'm glad of any official news we get, but I'm not letting my hopes get up too high just yet.
