Android and ChromeOS will converge.
Like all ostensibly sensible ideas, this is probably a bad one. The whole point of Android and ChromeOS, right now, is that they're "playful experiments", tweaking Microsoft's tail, exploring new markets. There's no point Google having a big, boring engineering consolidation project to bring them together. That's just going to alienate internal developers ("but this is my baby!") and confuse third-party developers ("shall we wait for the convergence?").
Better to have a reasonably decent Android emulator running on the ChromeOS machine so that Chromebooks can run Android apps.
Update : read the comments on this blog-post. ("this blogpost" meaning this one, on Platform Wars). Lots of good discussion there.
