My theory about the gun and that opening scene is that Walt is already done by then and there's no real showdown coming. His cancer is back. Walt J. an Skylar are dead, possibly even Hank and Jesse. Walt has gone on the run. The final scene will be him taking the gun out of the back of the car and coldly opening fire on the headquarters of grey matter.
Lol, ok not really since they showed the gretchen and the other guy live in ABQ, but it would be a huge difference to how people expect the show to end.

What a fucked up ending that'd be.
I marathoned it myself once I got into it. I couldn't stop. Very addictive.
It would have been mouldy and smelly by then so I guess not. However, that's how depraved Walter's been, enough to make me wonder. But he wanted to do right by Jesse, so that's what made me think the cancer's back. On some deep, psychotic level, Walt cares about Jesse just a little bit. Obviously Jesse thought Walt was going to try something; that's why he was armed. Perhaps Walt's affections aren't returned any longer.
