Well, none of us thought they were going to happen this generation (at least I really hope so), but still, if you weren't convinced by the generalized mad rush to end gen 5 ASAP, as well as Junichi Masuda strongly implying not a single man-hour had been invested into such a project late last year, today's announcement will crush any hope you had.
To celebrate the 10th anniversary of Ruby and Sapphire's Japanese release, various retailers are going to be distributing Kyogre (for White 2 owners) and Groudon (for Black 2 owners). I mean, just think about it. If they were planning on making these remakes, why the hell would they distribute Kyogre and Groudon to begin with? Yes, the answer is as obvious as it sounds. They're. Not. Happening. At least not for the next, say, two years and a half at best.
