900 million. I believe both this and Cap 3 will stay, so that will definitely cut into the bo, although not as much as people would have you believe. Also think a small contingent are going to be discouraged to see this after TDKR and MOS.
People being discouraged? That's like saying 'people were clearly discouraged' by the first(and second) transformers films so I choose to focus on that 'fact' and predict the worst. Yes good luck with that.
TF4 currently predicted as the film this year with the highest(if only) chance to hit a billion. Each installment in the franchise making considerable amounts of money and more importantly, considerably more than the last and all that without being the prequels to some event trilogy. All that in the face of 'fans' shouting they suck, fail and no one likes them.
Secondly I find it all so convenient in light of just how many people 'marvel has discouraged' with their films(prior to cap2/ prior to avengers). Instead of looking at who has been discouraged, perhaps a focus on who has been encouraged would do us some good. Last I checked MOS opened bigger than any other cbms starter, and it went on to (arguably) gross more than any other one save for spidey one and with tons more competition. It's been winning hand fulls of pop culture awards and it's dvd sales are through the roof(particularly relative to it's competition). Just who is encouraged by the prospect of the sequel? I'd argue a hell of a lot more people than there was coming out of the last few Superman films at the very least. All that without even mentioning Batman's return.
Thirdly and into another issue; of the people whom aren't encouraged by these productions, such as yourself, how many of these people(such as yourself) aren't going to watch BvS? Can I assume you aren't?
I can tell you that as let down as I was by avatar, I'm going to be there on the first night to see the sequel! It's one thing for detractors to talk, but there is rarely any follow through in this regard. Event films happen and people who like movies go watch them, it's really that simple.
This reminds of of when people(predicting sites included), threw around sub TDKR numbers and mostly IM2 numbers for Avengers and for various logical reasons. Shame we can't all learn from the past and see what's clearly about to happen here.
Lastly, you must be one of the few people I've encountered that actually thinks both studios would commit to losing that much money. Most people I know see this a game of chicken and the issue is about who will pull out first, not so much a game of whose actually willing to lose more money. I tend to agree with the latter. Guess we'll see.
