From TF2 Wiki

Info

First revealed at the July 2006 EA Summer Showcase event, this trailer showcased Team Fortress 2's dramatic change in visual style and gameplay from its initial design.

The trailer, since it is showing a early rendition of the game, contains several differences from the final product:

• The general design of all the characters is somewhat different. it is more apparent in some classes than others, such as the Engineer and Soldier.

• The muzzle flares were changed to look slightly more realistic.

• The Spy's revolver is a Tranquilizer Gun.

• The Scout is shown wielding a Submachine gun, which was later replaced with a nailgun and finally the scattergun. The Submachine gun found its way into the hands of the Sniper.

• The Demoman is shown wielding and throwing a Dynamite pack (MIRV Grenade), a would be stay-over from Team Fortress Classic, which was removed from the game following beta and replaced with sticky bombs.

• The Medic is shown wielding a giant syrige, which was later replaced by the Medigun as Valve wanted to add a more distinctive indication of the medic's healing ability.

• The picture showing all the classes at the end is the outdated version featuring the older designs and weapons.

• The Pyro has a skull insignia behind him in the scene where he flames the camera which has not yet reappeared in any form. This skull was used for the Red Team's logo in TFC.

• The 2fort bridge is now covered.

• 2fort has also seen numerous other smaller changes like a different lightning in the basement room or the use of stairs as entrances to the forts instead of ramps.
