Yes, you get the one that's on the cover. That's how it always is.
However, sometimes you can also get the other one, and I don't believe they've confirmed either way, yet. So you might be able to get both, like in G/HG and S/SS for example.
That's why I was asking. I keep hearing people at my work talk about how they're changing it and they were trying to tell me that whichever version you get, you get the other games legendary. Which made no sense to me, so I guess they're morons. Thanks for the clarification though. Super pumped.
