All I'm hoping for visuals wise is the same chuck jones style without that icky upressed feel you get from projects like the ios phoenix wright ports.
Yeah I'm always doubtful of projects like this when it comes to visuals. It's very hard to get right, especially because the old Lucas adventures (from Indy 3 onwards) have such a strongly defined visual style. I'm sure it'll be better than the Monkey Special editions because they're doing it inhouse rather than outsourcing it to Korea. Monkey 1 was especially atrocious. Monkey 2 was better, but I still feel a lot got lost there.
I hope they're willing to add a few frames of animation here and there. Just changing all the characters/objects/backgrounds to higher-res redrawn versions can make it look very odd - if you're going to change it you might as well add some things here and there to make the new style work on its own. That's one of the things the Monkey 2 remake got right, I think. They made the animation more fluid to make walking animations etc. not as jarring as they were in Monkey 1 SE, and added small animated background details such as birds/clouds/frogs/etc.
Double Fine mentioned on their forums that they're going for something inbetween what they did for Grim and what Lucasarts did for Monkey Island. They didn't go into too much detail beyond that, but I guess what you can expect is something like Monkey 2 SE without them reinterpreting what certain characters look like (I'm mostly talking about Guybrush - Guybrush in the first remake looked horrible, although he looked better in the second remake. I don't think the Monkey 3-style lanky Guybrush works for the first two games, although I admit that he's an especially difficult character to get right given that he's so iconic and the original sprites don't give you a lot to work with - the bigger, more detailed sprites of DoTT should be easier in that regard. I did like that they gave Monkey 2 LeChuck a dead crow in his hat, which is a detail that only showed up in the original concept art by Steve Purcell).
I'm mostly excited for the remake (and any upcoming remakes) because of the new music and commentary tracks though. I really hope they went the extra mile and got Ron Gilbert and Gary Winnick to record a seperate commentary for Maniac Mansion, which is playable on a computer in the DoTT mansion. I don't think it's realistic to expect a full remake of Maniac Mansion within the game as that would pretty much require them to remake two full games (and I don't really think that's needed at all), but a commentary would be really neat. Would be some nice exposure for Gilbert and Winnick for their kickstarter game as well.
