What is the next windows phone to be released/what will be special about it?

Hi, I want to buy a Windows Phone, but most of them are about a year old and I would assume that a new model might be coming in soon. I was thinking of getting the LG Quantum. Is there any phone coming out in the future that is worth waiting for?|||Its not the phones to look forward too, the new update for WP7 is coming out soon, Mango. It'll be awesome!|||All the windows phones will be getting the Mango update. There are a few new HTC and Nokia phones too in the tunnel. I will suggest you to wait for couple of months.
