Well I usually play with one of my brothers, back in 2003 I got Ruby and my older brother got Sapphire, so maybe I'd like OmegaRuby, but my older brother doesn't play anymore but my younger brother does, so he will no doubt have a say.
I'll be able to decide when I find out the revised story more and see if I can fit it into my Headcanon, I don't think these will be straight remakes, they talk about a new world and new story so I might get OR as my sequel to R, but if it is the same story then I might get AS as I've already played the Ruby story.
But to be perfectly honest, I redid Emerald only last year so not really keen to go back to Gen 3/Hoenn so soon, and hope it's not the same plot.
Usually, I buy the same version as the original, but this time, I'm getting Alpha Sapphire because every version of every Pokemon game I get never has Kyogre, and I'm sick of never getting a new one. (Especially tempting now that Kyogre might get a Mega Evolution. A Mega Evolution of the most dangerous Pokemon of all... I can't go without one!) I might change my mind is Omega Ruby has a really cool feature that isn't in Alpha Sapphire, though.
