Exactly. Super 8 is a wonderful tool with unique abilities and attributes, use it as such without lamenting its pronounced grain, etc.
In addition I don't think that a new super 8 camera would need many additions, I certainly would NOT want a super 8 camera with and LCD or EVF as others have suggested, a video tap would be o.k. but not on my list.
A new super 8 camera that would be teriffic would be 16:9, have interchangable lenses, a big bright viewfinder with TV safe and 16:9 markings, it would have vairable frame rates from 0 - 100 and be constant at 23.98. A longer load would be great as well, a good battery system, and a good 2 stage matte box and rods would finish things off. That is about all I would want, well O.K. I would love the ability to shoot with swing and shift lenses on super 8, that would be amazing, but I know it will never happen.
Also a new camera could drop some old features that are not really necessary such as auto exposure, and in camera dissolves.
