It resolves naturally to E major, although as Sean was saying, you could make it resolve to A if you wanted.

Can I just clarify with somebody that this is the correct way to figure keys out: look for either two major chords or two minor chords together (e.g: A, B). In the case of major chords, they'd be the 4th and 5th of the scale which makes the key signature E major.

Is this right?

In this case, the logic fits.

Say you have a progression that uses many major chords, like E G A B C D (all major). You should look into modal mixture (in this case, it's in E major, using the I IV and V and borrowing the bIII bVI and bVII from the parallel minor, E minor). There are also other major chords you can substitute to, so just make sure you watch out for those.
