If you really can't wait, there are still some good options. The S III is one of the best phones ever made. The Note II is just as nice as the Nexus 4 and the S III, but it might be too big for some people, myself included. Also, you might be able to find the Galaxy Nexus, which is the phone I currently use. The Google version is no longer for sale, but you might be able to find a brand new one on Ebay, or if you aren't comfortable with that, some of the wireless carriers might still be selling them.

If I could deal with the size and pending a usable CM10 build for it, a Galaxy Note II, which is essentially a giant-screened SGS III with monstrous battery life and a pen (which won't be usable under CM10).
Both support 64GB microSD cards, unlike the N4.
