In the coast video we can see that the player has the regular HL-inventory and can choose from a good bunch of weapons.
In the coastline video we can see Gordon throwing away his shotgun in order to pick up the missile launcher.
The later makes more sense to me.. although I think you should be able to have two large weapons like shotgun, machinegun, missile launcher and such, one in his hands and one on the back. Two pistol size weapons could be carried and a few other things like HG, mines and so on. Plus the crowbar of course
This way you would have to think ahead somewhat and decide which weapons you can't be without. This worked very well in FarCry 
Which way is it in the final version? The former I guess :|
