I don't have an official answer to this, but I would imagine there will be some print corrections.The 1st print had a couple of inconsistencies in the new race descriptions, and the extra colony ships were missing the cube symbol. None of these things are game breaking and the player boards don't seem to have any issues.
1 thing that you would likely be missing out on is the bonus tractor beam rare tech that was included with a handful of corrected tech and ship part tiles.
So I'd say if the purely cosmetic corrections are important for you, then you may want to grab a new print copy. If you're more interested in having tractor beam, then I'd say you should try to get a 1st print copy.
I am unsure if the 2nd print has been released yet or not though.
