According to this reivew, P4 is about hard as SMT games get.  
While we can all agree Persona 3 and Nocturne were fairly easy games (on standard difficulty at least), the preview brings back memories of the first Persona and SMT 2.  
Will this be a game that needs serious grinding and faq searching? Seriously, the game with the ugly yellow look?
 

Given the player reviews over on Neogaf, it's hard, but only because of the new elements and such. I don't mind it one bit because I love hard games. They force me to use a little more strategy every now and then.
 
Also, it is just me, or does the reviewer seem to be implying that he found Kuma annoying with the whole Doraemon section?

I don't think he was implying anything as much as he was outright stating it. And having heard both Kuma's and Doraemon's voices, I can say that he absolutely right. Seriously, they could just slap a sound clip of their voices in the "annoying" entry of an online dictionary.
