Sony streaming PS4 = Current Game collections/hoards worth more, or less?

[Gameguy]

If the new trio of consoles is streaming only, and one cannot have content physical (discs, maps, cases, art work)
Will gaming collections/hoards be worth more or less in the future.

Are collections worth more or less now that every game can be downloaded and played for free on an emulator or flash cart? There will always be people collecting this stuff.
