Is it still worthwhile to buy a Nexus 4 now?

I've been wanting to get a Nexus 4 for a while, and now they're finally in stock in the Google Store, so was thinking whether it's still worthwhile to get one now or wait for the Samsung G4 or whatever Google is releasing in May...

The only downside about the Nexus 4 which makes it worthwhile to wait is the camera - I've used the Nexus 4 and found the camera on my iphone 4 to be better, despite the I4 being slow as molasses compared to the N4.
