Based on their past rate of progress, I can't really argue that. It may be next year, but I think they will try very hard to release Galaxy before Autumn. They seem to be on a set timetable now, hence the somewhat premature release of Power.It would be nice if shipyards could be fixed once the big changes to ships are done. i.e. after the weapon update, fix the new issues and the old recurring never-fixed issues.
In all honesty, we'll probably be waiting a year for the universe update, if not more. But hey, surprise me, Schema. Go right ahead.
I'm attempting to take schema at his word that updates will be easier and faster now, after the power update, but I'm still assuming that major projects like rebooting weapons will take a very, very long time. In fact, I think the Weapons phase will be the longest of the current "2.0 Cycle" because it won't be "just weapons" it will be weapons, armor & effects, then fixing weapons, then balancing them to power, balancing them to shields, balancing them to armor, balancing armor to shields, then a ton of combat testing to determine other critical balance issues with the relationships between power, weapons, shields and armor. They're all so intertwined. It will take a lot of back and forth, plus debug. Yeah; it'll be many months before the game is functionally re-balanced after Weapons release.
I'm cautiously optimistic about Galaxy though, because of what we know has already been done, and the fact that it is less interdependent upon other systems. New planets, intelligent resource distribution, and leviathans seem to be all wrapped up and waiting under the tree like presents for Christmas. Once the 2.0 system revisions are stable, they don't really have much to do to release Galaxy. So they seem content with the broad strokes on power right now, and it would be hard to balance it much better without testing it context with new weapons & effects... I'm guessing we will be seeing initial Weapons-related updates begin within 30-60 days.
But based on track record, it could take a lot, lot longer.
