Ebooks are touching or have crossed 50% of sales in certain combinations of markets and genres. Overall they make up 30-50% of all book sales. So no, print books aren't still the vast majority.
I remember reading on Charles Stross' blog that the paperback is kind of dead in the US. At least for his niche. I think his last book only went out in hard cover.

And ebook instead of paperback, of course.
Also worth mentioning that there are some genres that will never make sense as ebooks.
When was the last time someone bought you an ebook as a gift? This is is the main market for cookbooks, for example.
