Xenoblade, The Last Story, Versus XIII and Ni No Kuni haven't been confirmed for 2011, and there's no way Versus XIII will come out next year. I read a preview for Ni no Kuni where the writer praised the graphics, but was a little let down with the gameplay. Don't remember the reason why. I think it was from RPGFan.
As for Disgaea 4, yes, I do think you need to say more. I liked the first one, and the second one was alright. But I got bored with the third one. Gameplay wise, it was more of the same, and the story/characters didn't do it for me. I didn't find this one funny nor interesting. IDK, maybe I've just grown bored of the series. I'm skipping part 4 unless I hear something that interests me.
2011 is looking more like the year of WRPGs. Just look at zarx's post.
