Yes. The average consumer doesnt know, doesnt care, or both about the Sony/Fox/Disney split. Spider-Man and the X-Men still sell a ton of money, and I still think a few X-Men characters are still counted among the most popular Marvel characters. I bring up the average consumer because actual comic book fans are going to be a fan of any of these characters regardless.
The Avengers have become way more popular than they used to be, and are being pushed more so in a marketing sense. But I don't think that necessarily means X-Men and Spider-Man have been dethroned.
