I doubt that there will be, the days of the networking industry being
driven by that sort of thing have been gone for some time.  Even the 
iphone for all it's coolness, has not caused the majority of cell phone
owners to run into the store and upgrade their phones.

But what there WILL be are the millions of NEW Internet users who get
on with only IPv6, and some kind of IPv6->IPv4 translator to get at
the legacy stuff.  That is already driving the content providers to get
on IPv6.

The process of switching end users to it will be more gradual but
honestly, corporate/organizational/business use of the Internet has 
LAGGED residential use of the Internet for MANY YEARS.

When Sally Schmoe the Marketing Manager throws her old home laptop to 
the kids and buys a brand new one that speaks IPv6 out of the box
to her home DSL line, it will not be long before she is in the network
admin's office demanding to know why this cool app that is IPv6 only
that works great at home isn't working on the company network.

She won't give a tinkers damn that it's because the corporate network
admin is going slow on IPv6 deployment, in 2 shakes she's going to be
in the CEO's office peeing in his ear about how incompetent the network
people are if you don't have something for her.

At least, that's how it's always worked in the orgs -I'VE- worked at.

It will come, just wait and see.  Have faith.
