Post 500! Wee! 
In regards to the new lighting:
“Let there be light!”
“He shall light the way.”
In regards to the stages:
“The end is nigh!”
Looking at the screenshots of the lighting, I particularly like how much scarier Sabrewulf looks as a result of the changes. I hope the rest of the cast looks equally, if not more so, as great as that.
I’m thinking (and @Rukizzel, feel free to correct me if I’m wrong or simply reading too much into this) that by 3 NEW stages, there will be 3 MORE stages for S3 - and since we’ve already basically seen the stages for both Kim Wu and Arbiter, those don’t count as “new” per sé. In other words, there’s actually going to be 5 stages in total for S3, not 3, which may also mean there’s going to be 5 characters (and if I had to hazard a guess as to who they are, it’d be Rash, Kim Wu, the Arbiter, Tusk, and Gargos - the last of which may not even be playable at all and if that’s the case, may be replaced with the proposed and formerly mentioned discarded vampire character, which in itself, like Gargos, has not actually been confirmed or denied as of yet either). Then again, @Rukizzel’s statement was pretty straightforward and succinct - and if that’s the case and there truly is ONLY 3 STAGES, then well, as fan, that makes me want to cry…
…and hope that there’s a LOT more to S3 than they’re letting on.
If it turns out to be only 3 stages and the 4 confirmed characters (Rash, Kim Wu, Tusk, and Arbiter), along with the S3 adjustments, menu adjustments, and new lighting at release - I will be absolutely bitter after having waited so long. If that’s what you’re doing to me, IG, then I’m letting you know in advance that, in terms of content, I think you’d be dropping the ball. So, please surprise me, show us something more in the coming weeks, and prove to me that I won’t be disappointed with what you have on offer for us. Do that, and you will score with me, big time…
