Yes. I would actually prefer something more like BW2. Although:
^This.
I don't care if the game is a 3rd version like Emerald, Platinum, a sequel (like B2W2), or even a prequel. The only thing i want is another game (yes, a single one but with changes like the ones made in BW2) to finnish Gen 6 properly, one that includes the core aspects from the first pair and expands. Meaning, the same region, Kalos, but with some changes. The same starters (with the possibilty for Megas). Also, the Kanto starters and legendary birds too so I could get the 3rd member I didn't get in X and Y. Preferably, a new story would be cool (like BW2, either a sequel or a prequel) but is not an absolute requirement to me. Zygarde and all its formes. AZ's Floette made available and all the misteries solved. And finally, Post-game content!
The reason why I like Platinum and BW2 much more than the initial pairs is the ton of stuff they put in those games so we can still have fun and something to do after the main story. Pratical things like Join Avenue with those training shops, the World Tournament or a Battle Frontier (although I'd prefer something more like Black Tower/White Treehollow so you can get experience), new areas to explore, and a reliable way to rebattle Gym leaders and the E4, like Platinum did. Or a place like the stadiums in BW/BW2 where trainers have high leveled pokémon. I just want all that in a gen 6 game.
