Google really needs a differentiator here, and they are pretty good at that. But all I can foresee is, "Google Wallet (Beta), currently open only to US users" and the beta running through years. If Google can open it up to the world fairly quickly, it will definitely have an edge over PayPal, which is very much US centric.
Google just might be the one big, yet nimble enough to pull it off.
