I'm afraid not. Kingdom Hearts was released for the Playstation 2 featuring groundbreaking graphics and cinematics for the day, then Kingdom Hearts Chain of Memories came out for the Gameboy Advanced, which used an awkward turn based battle system involving decks of cards. Next came Kingdom Hearts 2 on the Playstation 2 again, which improved upon everythng in the first game but was somewhat easier due to the massive amounts of skills/powers you could learn.
As with the secret ending of Kingdom Hearts 1, the plot of Kingdom Hearts 2 was left at a cliffhanger, but instead of starting development on the much rumoured finale Kingdom Hearts 3, Square-Enix announced a trio of prequels to shed light on all the unanswered questions about certain characters and plot elements. Over the next several years Kingdom Hearts Coded was released in multiple segments as a Japanese Mobile Phone app (our phones weren't up to the specs), Kingdom Hearts 358/2 Days was released on the NDS and Kingdom Hearts Birth by Sleep came out on the PSP.
Naturally the suspence for Kingdom Hearts 3 has been building up to a climax, but although development is well under way Square-Enix announced that a further title (Kingdom Hearts Dream Drop Distance) would be making its way onto the N3DS before Kingdom Hearts 3 will end the series on the PS3.
