If the funds were available I'd rather see the story finished properly than remade. As was pointed out, how many ways can you kill Roy.
There are so many stories to tie up and progress with that remaking the series IMHO doesn't make any sense.
I've only just discovered the intricacies of Macross (too busy being a macho jock in my younger days) and I would love to see a bit more effort put into closing the story.
