Before KH3 comes out, I believe Kingdom Hearts II: Final Mix will be released. Even the release date for that game is unknown, so it could be a while before we hear anything of a release date for Kingdom Hearts 3. (I am improving this answer because Tetsuya Nomura said that he was never going to bring the game KH II:Final Mix to the US,he said it will remain in Japan.)
Kingdom Hearts 2 Final Mix or Final Mix+ will never have a release date here in the US. The game along with Coded and the original Chain of Memories is a Japanese only release. However you can be like me and go out and learn Japanese and buy the game over eBay. The game is being sold (not in stores) around the US and other parts of the world but if you cant read or under stand Japanese you wont get far in the game.
Kingdom Hearts Birth By Sleep is scheduled to be released on September 7th, 2010.
the creators don't even know man (message posted 11-5-09 November 4:24pm).

between 2010 and 2011
Kingdom Hearts 358/2 Days, which has just come out in Japan, and is due for a late September release in the US, and is for the DS. Kingdom Hearts Birth By Sleep is for the PSP and does not have a release date yet.
In order of Release These are Them kingdom hearts kingdom hearts 2 kingdom hearts:final re mix kingdom hearts chain of memories kingdom hearts re:chain of memories coming soon:kingdom hearts re:coded and maybe:kingdom hearts 3
In 2010, there is not set date yet
It may never come out in America, or anywhere, for that matter. The only ones who know the answer to your question are the people at Square Enix and the creators of Kingdom Hearts. Your question is frequently-asked, and it won't be able to be answered until Square Enix sees fit to tell the public. If Japan finds out when, we will, too. *KH3 may never come out for PS2, because PS2 is no longer a major system, because of the Wii and the PS3's sudden rise in popularity. But you can look forward to some KH DS releases such as: Kingdom Hearts: (Re:) Coded-For the DS Lite, DSi, and the DSXL, a possible continuation to KH2, no actual plot has been released to the public. Expected US Release date: Late 2010 to Mid-2011 Kingdom Hearts 3D-For the 3ds, an exploration of Sora, Riku, and Kairi's full adventures during the first Kingdom Hearts. Expected US Release Date: 2011 Kingdom Hearts: Chain of Memories DS-A DS version of Kingdom Hearts: Chain of Memories. Expected US Release Date: 2012 Kingdom Hearts: Organization XIII-An exploration of how all of the Organization's members came to be. Expected US Release Date: Mid-2011 to Mid-2012
Sqaure Enix announced that Kingdom Hearts Birth By Sleep is scheduled to be released sometime during the summer of 2010 in the US and the UK.

Kingdom Hearts Final Mix and Kingdom Hearts II Final Mix+ are Japan-excusive games and are not scheduled to be released in the US.
It's currently unknown if the manga by Shiro Amano for Kingdom Hearts: 358/2 Days will be released in the United States and the date is unknown.However, Tokyopop, who has been licensing the Kingdom Hearts Manga Series will put an update up when they decide to license it and release it. Right now they're still working on Kingdom Hearts II Manga and 358/2 Days is still running in the Japanese Square-enix magazine.
