Unless that bank is shared between characters i see no use for it as i have 1000 inventory slots. 
 
The skill points sounds nice though.

cool! i enjoyed the last dlc cant wait for this one. better get more points.

If this DLC is anywhere near as good as the first, then I'll definitely be buying it.

Fighting Flynt and Sledge at the same time? Vampire and low-gravity mode? Loot bank? I'm listening. But the skill points thing seems like a balk. I wonder what else they're up to ...

You had me at Borderlands!

So is this like Horde and Firefight for Gears of War 2 and Halo 3: ODST, respectively?

Aw, damn...i was kinda halfway expecting the next DLC to be Christmas themed.

" Via Kotaku: 
 

Update: Gearbox Software says that Mad Moxxi's Underdome Riot is "not just new deathmatch areas." CEO Randy Pitchford notes "This is an ENTIRELY NEW GAME MODE."

"Think [Halo 3] ODST's 'Firefight' or Gears of War's 'Horde Mode.' Cash, prizes and competition!" Pitchford said in a statement from Gearbox. "It's like Smash TV in coop FPS, but in the Borderlands."

Gearbox reps say the new Borderlands downloadable content "expands greatly on the possibilities of combat as well adding a ton of new rules such as vampire mode or low gravity mode..." 

 Sounds neat, very neat indeed.    "

"The arenas featured in the DLC are not PvP arenas, it's a questline that takes you to several different coliseums that feature different challenges. Of course, the possibility of an additional PvP arena is there, but that is not the main feature of the DLC. "

We got zombies and now vampire mode.  I'm expecting werewolves to show up in the 3rd batch of DLC. 
 
Have yet to buy the first DLC... I'm trying to enjoy all the goodies I bought this year and holding off to buying anything until next month.

I would have bought the Zombie Island DLC when it was released on PC yesterday, but saw that it had 5-machine activation limit SecuRom (even on the Steam version!).  So as much as I enjoy Borderlands, I can't support that.  Not until it's removed or it goes on sale for $2-$3 or something.

The areas sound pretty cool especially when you throw in vampire mode and low gravity. Hoping the bank is accessible to all your characters but I doubt it.

I hear from a reliable source that Tim Schafer is co-developing the third pack to cram in some inappropriate RTS elements.

The bank makes this pack an automatic buy for me.

Fun times!  I can't get enough of Borderlands.

I got through about 70% of this game before I got REALLY bored with it. Brought it straight back to the store.

Cool.
