Indeed. This game is still Alpha/pre-Alpha.
Q2 is basically a wash-out, and realistically at this point we're talking maybe Q3 2015/Q1 2016. Why? Because a decent Beta takes around 3-6 months (or has in other Paradox games), meaning the chance of this being done by the end of Q2 is very low. Paradox have previously stated that they won't release their games in Q4 because then they would be up against the Christmas launches of the big-name companies, so missing the Q3 window basically puts things back to Q1 2016.
Of course, some people will want to get angry about this, because they see a release date that was predicted to the nearest quarter as a promise of sorts. Personally I think the "it'll be done when it's done" attitude the best one - we've seen games that were released before they should have been, and it wasn't a pretty sight.
