The Koalition: "Fans of the Kingdom Hearts series, including me, have had our patience tested since the last numbered entry (Kingdom Hearts 2) was released in 2006. Almost 7 years later, we still have yet to see the next official numbered entry in the series. In its place, Tetsuya Nomura and Square Enix have released side stories and prequels–with Kingdom Hearts: Dream Drop Distance and Kingdom Hearts: Re Coded being the only portable titles that actually progress the story. The fanbase is quite frustrated to say the least. Kingdom Hearts 3 has to be on its way soon, at least I hope.
That said, I’ve kept an open mind about the portable titles (at least Kingdom Hearts: Birth By Sleep was teased at the end of Kingdom Hearts 2), which contain concepts that I think Nomura could expand upon in Kingdom Hearts 3. While there are many things I want to see in the next game in general—closure, for one—this list will focus on the concepts from the portable titles that I think could be adapted or expanded in the next game."
