That's the point - there's almost none pointed to .io. That said, I think it's pretty dangerous to create an SEO strategy around speculation that google "might" change the rules around something as big as a gTLD.
I'm not saying it won't happen, but if you're specifically hoping to gain traction via SEO efforts, using a ccTLD that Google hasn't explicitly mentioned as ranking like a normal gLTD I think you're taking a big unnecessary risk.
