Yep, it comes with the exclusive memory card :)
I thought about doing that, but at this point I'm restarting my game, just so I can get all of the starters for pokedex purposes. I may end up doing that, but I think I'll be restarting over a few more times, just so I have male and female copies of the starters. With no dittos in R/S breeding is a bitch :/ After I do all those resets, yes I probably will be erasing the memory card data, but for now It's gonna be the game cart resetting :)
