Bad Time to Invest in Surface 2?

Hi all, so as the title suggests I am thinking about purchasing a Surface 2. My laptop is on its last legs and will need to be replaced quite soon.

I don't do much on my laptop besides browse the internet and consume (way too much) media, so I figure I don't need full Windows. I know a Surface Mini might be on its way soon but the device doesn't really interest me. What does interest me is the direction Microsoft is taking RT. I am curious as to what version of Windows that'll run to see how committed to RT they are.

Am I better off waiting to see what Microsoft says at the hopefully soon Mini announcement or should I just pull the trigger?
