I never read manuals. For collection purposes they're neat and I would like them to continue. but games have in game help files, and tutorials which negate their point. So then it's in there for mostly aesthetic reasons.
Of which company's can market collectors editions/or give preorder bonus's like with catherines art book/sampler for people that care about aesthetics and make more money.
Nor is there a huge uproar over the games that don't have it which pretty much guarantees there demise.
