Obviously I don't own Alan Wake yet since it isn't out. I'm still between RDR and Alan Wake for the game I buy on May 18th and I'm leaning towards RDR and passing on Alan Wake for now. I'm judging Alan Wake's lighting from the videos I've seen of it. If you're talking about God of War 3, then yes, I do own and have played it.
Actually, if the DLC comes will all new copies of the game like Heavy Rain's did, I might get it day one even if I might not play it right away. The bigger problem is time to play these games.
As for the transitions, I'm almost positive I'm not alone in thinking the animation transitions in Uncharted 1 were wonky. It wasn't as weird as Tomb Raider Underworld, which is like an extreme version of it, but it was still a bit jarring. One of the big improvements to Uncharted 2's visuals were making everything more consistent and smooth. And it is just the transitions. I think Uncharted and Alan Wake seem to have very nice animations regardless.
