I start to understand.
First apology would be on it's place for throwing blunt facts about you by blindly assuming things . I should have asked instead of assume.

Then next, I do not think we should wait for the next adventure to emerge, rather than start our own adventure and see what comes out of it. We could wait for Sony and Bungee to cooperate and invent the newest 3D Screen with the newest series of games, but that would be just another big spent of money rather than really participating a new adventure. IMO it'd only be an adventure for Mr. Boss-of-Sony swimming in money. Like it went for the Wii (not saying that nintendo doesn't have all rights to do so).

I don't think something NEW would happen again if you wait. If you start undertake something and share vague new ideas and ask people to cooperate however, who knows what could come out.

I don't have an answer for your question (YET! ) but I don't think there are none new breakthroughs to come anymore. Yet, I can not deny that the past 8 years have brought less, way less NEW things for public than the 8 years before 2000.

EDIT:
The thought in your above post crossed my mind, and I have to agree on that one. But even if there seems to be no improvements anymore without new fancy hardware, doesn't mean there aren't any to be made .

It took humanity a while before Velcro was invented. Sometimes the obvious is overseen for a long time .
