I don't recall Badland Games ever stating that the Velocity 2X DLC would be distributed with vouchers nor that the documentary wouldn't be on-disc/card, and that's not what I was talking about. What I and everyone else is complaining about is that they advertised a physical soundtrack and a paper booklet with the Vita version, which weren't included, and even the front cover of the game advertises those extras.
Velocity 2X is priced at $29.99, and with the Vita version, you get absolutely nothing but the case, cover, and game. The PSN price is $20, so LRG would've priced it the same. The key difference here is that LRG has never once promised to include a soundtrack and manual with a game, took people's money, and then shipped them the bare game. It'd be like if, after the endless wait, LRG shipped bare copies of Skullgirls, without the extras. Badland Games pulled a total bait and switch, and so far the only thing they're owning up to is that the cover was misprinted.
