Thanks for the link, AdAstra.
Well, now we know it (again), as soon as they are happy with the formula the game could be ready in 12-18 months... so I suggest that we all shall meet again in 12-18 months.
Until then.
I wouldn't be too happy, that link was over a year old, and they said 12-18 months THEN, as in it's already been 13 months since they said that.
