There is, apparently, new errata in the SG reprint that was gathered before I got the errata gig; the 2014 corrections were left out, though I'm not sure why or what happened there. I'm working on getting hold of those changes and getting them posted.
As for the core rulebook being "out of print": Much more common, industry-wide, than you apparently believe, since you appear to be confusing "out of stock" (there's no more, or almost so, in the warehouse) with "out of print" (it's probably OOS, and they are no longer ordering reprints). OOS isn't a big deal; it happens a lot because the distribution channel buys it by the pallet-load. The SR5 core book has never been OOP; the SR4A core book is, however.
Doom-saying helps no one, Tytalan. Please do us all a favor and knock it off.
