Buy a Lumia 928 or wait a few months?

Hey everybody. iPhone 4S user here. I am seriously considering finally switching to WP now that Verizon has a good WP device. My concern, however, is that device is really a six month old device. What do you think? Jump on it now or wait a few months? Knowing Verizon, it might be a while until another good WP device shows up.
