Great points. So do you expect Spiderman 2 to struggle in this climate?
Or your point is that they want another billion dollar movie.
Sony doesn't have the cross over options that WB/DC has for one so they are stuck on their path. And to answer your question, ASM 2 will do about as much as MOS2 would do without batman, though I think with the universe building MOS2 would have trumped it.
Here's my stance.
I think WB looked at how well TDK(with ledger) and TDKR(without ledger) did in the face of marvel films, pretty darn great. Then they looked at how well these two bad boys did in the face of Avengers and they quickly had a board meeting. It's not just that the huge batfilms didn't make as much money as Avengers and all the residual profits going forward that avengers has allowed(a raccoon movie), it's that they got out buzzed that year and pretty darn soundly.
Everyone was talking about the Avengers event and as as good as TDKR was(to some), not as many people were talking about Batman. Why go through that again when you can side step it.
If this Con has demonstrated anything it's that WB has the cards to out play Marvel. WF kills so many birds with one stone and what's more it doesn't completely compromise the superman story/journey in a way JLA would. And the studio wanted a jla film for 2015 this is known. I think with Nolan out of their way(dude didn't want to share), plus the need to restart batman that will guarantee success, WF is just a given.
The best part is, WB hasn't even blown it's load yet. They can save their big JLA announcement for 2 cons from now and still have escalation. Marvel can't do that. Next con look for more dcu character announcements. and then in 2015 that jla bomb with drop and the con will be over.
WB played this right imo. Business wise things are looking up. Especially when WF out grosses Avengers two. Maybe they just got tired of all the bloggers calling them fools in light of Marvel's tactics.
