I wanna throw my hat in on the "Being Excited" verdict. I went on ahead and pre-ordered the game on PC along with the Season Pass while it was on sale. I've been itching to play more Borderlands 2 ever since all the excitement around Destiny, but I've been fighting that urge, knowing there is going to be all-new content in less than a week!
I totally get everybody's criticisms, though. I wouldn't buy this on a last-gen system, Handsome Jack (and Tiny Tina) were both received either hot or cold, and yes, there is going to be a ton of DLC... but I'm okay with all of that. Having spent hundreds of hours in the original Borderlands, having the sequel have -some- character and -some- plotline (whether good or bad) was an improvement.
