Planning on both, although I'm not sure quite yet just how intensely I'm gonna do the roleplaying aspect (that ended really poorly for me in SW:TOR, and I wanna get a feel for the ESO atmosphere before I invest too much into a character).

But on the whole yes, I'm on the preorder and I'm planning on taking a swing at RP at the very least. During the beta I rolled a super-fat argonian healer named "Steps Loudly," which I'm probably gonna do again, because it's funny as hell.
