I have 4 weapon slots and I'm always changing my setup. Due to this, it's hard to remember the order I equipped my weapons in, and I don't always know which weapon I'm about to switch to. When you're in the middle of combat, you don't really have time to sit there blindly flipping through weapons for the one you want.

That said, I think it would be a good idea to add small icons to the HUD (On top of the life-bar, on either side of the current weapon icon) that represent the other weapons in your arsenal. With this you wouldn't have to remember the order you equipped your weapons in, and you can see exactly which weapon you're about to switch to.

I suggest either "rotating" icons like so:

<- (W1) (((Weapon 2))) (W3) ->

or a more basic approach which shows icons for each equipped weapon and an arrow pointing down on the current selection (or it could just be highlighted or scaled up), like so:

v
(W1) (W2) (W3) (W4)

What do you guys think? I'm kinda surprised it hasn't always been like this!!
