I have a very nice poster from Airbus of the cockpits of the A320/A330/A340 and A380 all together. In reality you can hardly notice the differences.
Below I have tried to post a photo I took of the poster for the A320/A330 cockpits. The perspective is probably a little higher than the 3rd occupant seat, but my take is you COULD see the sidestick from this position. You make up your own mind...
Apols if the pic screws the page width...
