Source 2

• Being developed by 2K Australia and due out in the fall and is not being released for next-gen consoles so the PC version will most likely not be that much different than Borderlands 2.
• Set between Borderlands 1 & 2
• Not Borderlands 3
• Story wise you help out Handsome Jack. Not much else is known.
• Playable characters includee Athena from Borderland's 1 Genral Knoxx DLC , Claptrap from the series is also playable now named fragtrap, Wilhelm from Borderlands 2, and Nisha from Borderlands 2
• The setting this time around is set on Pandora's moon and will require you to keep collecting oxygen which drops of as normal loot (seems pointless)
• Two new weapon damage types Cryo (Freezes then shatters the enemy if you keep shooting) and lasers which can become massive.

My opinion?

I hope the game doesn't cost $60, $30 will benefit the game. Why? Bungie's Destiny which is also a game that blends FPS and RPGs mechanics like the Borderlands series is set to release during September. Destiny is also an MMO(-esque) game that is planned to have a 10-15 year lifespan (if successful). I do not see it competing very well since the hype is pretty huge, but it's not coming out on PC at launch.
We'll probably see memes as hinted by the game's title which is a shame if true since that's what I hated about Borderlands 2.
