Decisions, Decisions

I started a new job six months ago and the company is windows only. I ditched my Galaxy Note and got given a Nokia Lumia 800. I recently upgraded it to 7.8 but cant help feel that I am missing out on 8 especially to work the Surface RT they gave me (fantastic device by the way) So I was going to wait for the new Nokia to come out but then a deal for the Samsung Ativ S for £269 on Expansys appeared in the UK and now I'm torn with what to do. When will the new Windows 8 phones come out and what would they offer in addition to the Ativ S?
