They should do a definitive HD remaster of the whole series (improving on some of the flaws in later entries while they have the chance and including some lesser known titles) and release it on the Switch as well as PC.
I think a remaster won't be enough. They need to be remade. They're too old to be remastered and released as HD editions.
