No, your're right, this is what the $500 tier looked like before the update.
Same for the $250 tier.
Looking at the actual text descriptions that x2 might have been there by mistake though. Shame, as that would have been the tipping point for me to upgrade my pledge to $250+$30.
It gets even more confusing as the physical reward tiers start with "previous reward tier +" even though for many of them the next-lower reward tier is now a digital one that includes two digital copies.
On that note, what will I lose if I give away the single digital copy from a physical reward tier besides convenience? Will patches be available for the boxed copy? Will the boxed copy support all three operating systems?
