I think the issue selling out has more to do with the new status quo, and the speculator market.
That having been said, I am actually interested in this new direction. Much of the run so far has just been having good ideas that fizzle out, or rehashing ideas I have seen before. Even Matt in prison was done before, and everyone thought he was Daredevil at the time, so whatever there.
The annual where Mike Murdock got a life was the most entertaining where I am concerned, because it was different, and actually explored things.
However, I never read many solo Elektra stories, so they can rehash all they want, and it will still be new to me. If nothing else, her interactions with DD's rogue's gallery or other heroes would be interesting. Certainly different than if we had more followed Iron Fist in Brubaker's run.
Not to mention just what Mike Murdock will be like as he fills in for Matt. He is more or less a blank slate for possibility.
However it seems pretty obvious Matt will return in #666, and either Elektra or Mike Murdock will die at that point, given the whole Fist thing.
I'll be very let down if they go this new direction for Elektra only to have it be a typical Elektra solo. Her solo has always been her biggest problem for me. She's really not that interesting of a character.
