Do you mean Jason Statham. From his cameo as the Transporter in the airport terminal.
If so, that wouldn't make any sense. They might as well just have Cruise's character live, and pretend he faked his death. Of course, that wouldn't be a true sequel because it would have almost nothing to do with the original storyline. Cruise's character would have to been shown as caring to be given a reason to seek out vengeance (for losing the money he would have gotten as part of the job, or losing honor, or whatever.) I just don't see it happening.
Although thoughts of a sequel did come to mind after the ending (which sucked).
The movie stopped being good after the dance club scene where Cruise totally fucked everyone up.
Well Felix could give the hit to another professional. It does not have to be the Transporter.
Or they could maybe make the ultimate spy action movie and combine Ronin, Bourne, Collateral into one sequel.
