Yes he will be in 358/2 days as Xemnas. He is the boss of organization 13 which roxas is in (which looks like Ven but is not) and i think he is in the Key-blade War which is a real game coming out soon and in the game Kingdom Hearts 3 coming out in 2012!
You can go to www.egylines.org it's absolutly free
Besides the series of Kingdom Hearts, no.
The only Kingdom Hearts title for the PSP is Kingdom Hearts Birth By Sleep. Kingdom Hearts Birth By Sleep was released on January 9th in Japan and plans to come out sometime during the summer of 2010 in other regions.

Other games that have not been officially confirmed such as 'Kingdom Hearts 3' are not listed.
There is a Kingdom Hearts 2 Final Mix which is like a continuation of Kingdom Hearts 2. I'm not sure if there will be a Kingdom Hearts 3, but there are 2 new Kingdom Hearts games coming out soon. One is called Kingdom Hearts Birth by Sleep and it will be for the PSP. The other one is for the Nintendo DS and it's called Kingdom Hearts 358/2 Days. I hope this has answered your question.
http://www.gamespot.com/kingdom-hearts-ii/cheats/ here is a link to a great website that has the unlockables. and ignore the other person's answer because i doubt they have ever played any of the kingdom hearts games.
I would go to http://kingdomhearts.wikia.com/wiki/Kingdom_Hearts_Wiki and when on the website, on the left side of the page, role over Main Games and then click on Kingdom Hearts II. The website also gives you info on all the other games and so far has been a really reliable website, so you should be able to find out what Kingdom Hearts II is about, plus all the other games. :)
I own Kingdom Hearts 2: FinalMix+ and you can fight Terra. He is an optional boss and he is unlocked only after you have beaten every other world. After you have beaten the other worlds, return to the Disney Castle and go to the Throne Room (The huuuge hallway) and enter the small room at the other end of it. Here there should be a new crack in the wall where you will have the option to fight Terra (where it will teleport you to a new area for the boss battle). Happy playing ^.^
There is no true kingdom hearts 3 but there are multiple other kingdom hearts titles like Kngdom hearts 365/2
Since they are separated games from the other Kingdom Hearts, you'll have to buy it from online stores.
Hot Topic, You can go on-line at hottopic.com and search kingdom hearts and there's a kingdom hearts necklaces and other things.
Not really, i can get it in my local Games store , H.M.V ,Ebay and other websites too.
