However, additional merchandise doesn't necessarily release alongside the game that it's based on. What's more, the 30th October is a Wednesday — which typically isn't a day that's chosen for new titles. It's assumed, then, that The Veilguard's actual release date is at some point before the official art book drops.
Honestly, though, this supposed leak doesn't matter much anyway. BioWare's already confirmed that the game will be locking a date down this month, and that we'll be getting more gameplay to gawk at. Hopefully all is revealed sooner rather than later, so we can finally prepare our schedule for a new Dragon Age. It's been quite some time.
