Meloetta was showcased or how Genesect will be showcased.
Was any generation five years long? No. HGSS were released three years into Generaton IV; some people had already grown had tired of the generation. If the gap between HGSS and Black and White had been longer, the veteran fans who returned owing to the remakes may have very well lost interest again.And no, it wouldn't have made a difference at all. It didn't matter between Crystal and RS or Emerald and DP, so why would it have been any different with HGSS and BW? There's always been 2 years between a primary pair and the next games and no one flips the table.
I refuse to entertain such a terrible idea.GameFreak might not have been able to make a game that fully used the 3DS to its potential in that time, but they certainly would have been able to port BW to the 3DS and slap on a couple of features (not saying I would have preferred that, but I'm sure Nintendo would have preferred a Pokémon game with a "3DS" banner on the box).
