2. Is this a confirmation that i should stop waiting for the Anniversary Box Set and just place another IWM Order?
No. In fact, very recently Randall had a blog post stating that the boxed set is closer to production; he showed off the printer's proofs.
And I should mention, though it'll probably get lost in the chaff, that this edition of Tech Readout: 3058 Upgrade is a
reprint. It has a new cover and will be fully rebranded for Catalyst and Topps, and has had errata fixed throughout (and if you have any issues, please visit the errata forum RIGHT NOW and let us know!), but if you already have TR3058U then you do NOT need to purchase this edition; you will not be getting any new information.
