Suzaku switching sides?

Why the hell does everybody think Suzaku is going to switch sides in the next few episodes? I can see him giving up military life before joining Zero now as Zero was the reason Nunully was killed and a good chunk of Tokyo was blown up. Sure Nina gave him the nuke but he never intended to fire it and it was not until Lelouch's geass kicked in did he fire it. I mean he could be pissed at Britannia for building such a thing but Zero both picked the battlefield and made him fire it.
