Certainly it is, but every year we see this. Avengers and TDKR and Catching Fire all had around $1m in presales. The fact the Avengers did $200 million and the other two did $160 million speaks to the fact that $1m presales was the limit in 2012. Many cinemas today have reserved seating (all three in my area offer it). It's gotten to the point that you MUST buy advanced tickets to sit with your peers. The official prediction is $150 million. I'll wager it comes in around $170. But it won't top Avengers 1 or 2.
