I can't think of anything new, but I'll add my agreement to what other people have said.  
 
1) Fast travel in DLC 
2) Mini-map 
3) Companion (maybe a claptrap) for loot, etc. 
4) Weapon customization - I'm not saying a full fledged crafting system is necessary, but  add-on or upgrade drops (for mags, scopes, etc) would be nice. Also, a general purpose weapon upgrade kit. Example, if I have a level 40 gun I like, it would be cool to find an one-use upgrade kit that increases the gun to level 45 and improves the stats accordingly (Personally, I'm level 61 and still use a level 31 double anarachy SMG with nice extras - I'd love to upgrade that bad boy).   
 
In broader terms (Borderlands 2), my  suggestions would be: 
1) More story. Doesn't have to be a novel. Just something to add a little more personality to the game. Is it kinda sad when the best character in the game is a dancing robot? 
2) More NPCs. I don't want to talk to them or anything, but it would be nice if T-Bone Junction actually felt alive. Have people walking around, getting drinks, driving some cars (getting drinks then driving cars). 
3) Customizable characters. I want to make my own character. Both how they look and what type of "class" they are.  
4) Armor.

I agree that experience points seem very archiac and "gamey" to me. I much rather have skills that increase over time through use like in Crackdown - Use the ability and it goes up. Simple and more natural than a level system.

The exact opposite is Final Fantasy. Those games have crazy rules, classes/jobs, hidden stats... it's a mess and no fun for me.

I got my 360 in Dec 05. I wasn't planning on getting it so early since there wasn't much in the way of games out at the launch, but I saw it in the stores and couldn't resist. I played a lot of bad games while I waited for Oblivion. Which, by the way, is the reason I bought a 360 - I wanted to play Oblivion and I didn't want to bother with upgrading my PC.

So, I guess you could say I didn't really pick 360 as much as I simply quit the PC.
