I don't know. Unless the bug fixed is something REALLY big (like, the game does not start up or saves don't work at all big), they usually try to fix more than one issue per release, even if that one issue fixed corrects major balance issues. So I think there is going to be another "scan through the bug tracker and fix what we can" night before we get to see 5.010 pushed out.
But yea, I am also itching for a game. However, unless you choose the Spireling AI type, the chance of the AI getting Spire blade spawners as one of their first ship unlocks should be quite low, so you shouldn't be too scared to start a new game.
