To be fair, you also lose the Survival DLC pack, but that comes with all Gamestop preorders, so that's only an issue if you get the game somewhere else.
Most likely, but you can always ask if you can put $5 down. It was possible for the DOA5 CE (also GS-exclusive), but then again, that was half the price, so $25 might be the minimum for this one.
Honestly, I'd compare the U3 CE to the Survival Edition here, not the Post-Pandemic Edition that will more likely be "extremely limited" due to being GS-exclusive.
And just like the exclusive wearable replicas, and the Steelbook, you won’t be able to get this Sideshow Collectibles statue at retail, it’s only available with the UNCHARTED 3: Drake’s Deception Collector’s Edition! Like Nolan mentioned, this edition is being made in a very limited quantity, so make sure to save yours by pre-ordering now.
We've been lied to before.
