Like you, I would like to be optimistic about many v4-only apps and v4-only devices becoming dual-stack sooner than later.
But knowing that a significant (50%+) of android devices may not support IPv6 (just like my brand new Samsung Galaxy 7'' tablet (just bought over the weekend) being v4-only) and may not be upgraded by their users to the right software, and that Skype etc. apps are out there, my optimism fades away.
