Re: Been there, Done that
Yep, Bluestacks is one of the existing options/alternatives. Some current Bluestacks users have chimed in with questions/interest on the ConsoleOS Kickstarter page. ConsoleOS includes them in a comparison chart on their website, too -- this is probably oversimplifying, but I think they're ultimately going to attract people who use more than a couple of Android apps.
Another postscript from two days worth of Kickstarter comments: quite a few requests to support Surface Pro. The Mobile Media folks responded: "There's no technical reason why we can't [support Surface Pro], but there is some silicon in there that will require additional effort... it's do-able, but we need to know a lot of people want it first."
And if you're keeping score at home, they're approaching $18,000 pledged in two days.
