MORE new GTA 5 screens: new character, possible missions

[Update: you probably want the new GTA 5 screens here, or the latest Game Informer GTA 5 info here.] 

Continuing the GTA 5 screen attack are four new screens apparently showing a truck hijack in action and some angry police choppers.

GTA 5 screens & characters

The most interesting thing is that a different character seems to be the focus here. Instead of the old guy in the previous GTA 5 screens this seems to star a younger, bald guy who can be seen escaping police, hijacking a truck and shooting a police chopper.

What does it all mean? Will GTA 5 have multiple playable or fully customisable characters?
