That's sounds a bit far fetched to me. Maybe. But at that level of business one would think it would be about business and not emotions. However, having no access to anything I don't put much credence in that. Good chance it has something to do with the numbers as FF #10 (they rebooted the numbers a few months back and are re-rebooting them now, I think) ranked 99 in the sales lists.
Its kind of sad for tradition, as Marvel really launched with FF#1 back in 1961.
But the King must die eventually.
Really someone over at Marvel needs to take a step back, breath a little and think before the act. Its a huge property, with a long history.
