I've heard of this and will keep an eye on how it goes... while I enjoy Minecraft, I also find it infuriating in some respects.
I hope they don't go for the same block-based style though - I would like something that looks smooth, planets are round (ish), and gives a sense of scale. It doesn't have to be AAA quality artwork, just enough that you can believe in it.
The other things of course are how well a subscription model will go down in a world that seems to be moving toward free to play with micro-purchases (which I actually prefer, when done correctly), and how ambitious it is with this inbuilt computer system - it could put a lot of people off. I write code every day to earn a living, I enjoy it, but I don't much fancy learning anything beyond simple&fun just to get something out of a single game.
