iPad Mini refresh

Thinking off getting an iPad Mini soon, however I'm a little worried a new one will come out shortly, most cause I feel the SoC and 512mb ram is a little dated now, and apple is moving towards geting 1gb as standard.

My other option is to just buy it now, and sell it just before the refresh (Can sell it once we know the offical event date).

So what do you guys think, I am basically decide that I want a mini, after using an iPad 3, Nexus 10 and Nexus 7 for more or less 1 week each, it seems to be the perfect size, best apps, hate the aspect ratio for movies, but its awesome for the web.
