I'd be really surprised if Bungie chose to up to 1080p at the expense of having a terrible framerate. It'll be interesting to see how it turns out. Honest, if they don't stay pretty close to 30fps, I'd rather they just keep the resolution at 900p. The beta has me leaning towards getting the game, because it plays very well. Unfortunately there might not be much value in the expectations that are built from the beta. Here's hoping.
