I think a big part of this is going to be based on the success of the Marvel movies. They will attract new comic book readers and toy fans to the line. If those movies keep making money and drawing in an audience then the 3/34 marvel line will run and run.
Marvel Universe is going to thrive for a while yet, collectors don't let this stuff go and demand is very high for these figures. That's enough for Hasbro to keep running the line, even if it's at a reduced level.
I hope that the run lasts until I have space for nothing but Marvel figures.
