If they intended to release such a token effort, it would be out already - everything up to BSM has been remastered, and I don't think RW, The Real Thing or Capricornia need a remaster, so that only leaves 2 more albums to do (plus Scream in Blue, but I don't know if there is any potential to remaster that. I suspect we're more likely to see an all-new live compilation than a remastered SIB).
I'm quite sure we'll get more. I don't know how much more though - look at the Hunters and Collectors "Horn of Plenty". They gave the fans pretty much everything they could possibly want in a box set....and it ended up cluttering up CD shops for years. I think I bought mine for $50, and I saw it cheaper later.
