I have to admit I'm a huge Xeno fan and I love Takahashi to death, and also Mitsuda for that matter, but apart from the music what they've shown so far has not left me as impressed as I was by the two first XB games before their respective release. Don't get me wrong I definitely trust Monolith to produce quality gamepaly and genre defining mechanics as well as I trust Takahashi to produce an overall great game and a great story and background. I also trust that Ninty will only want this to be released when it's ready. So I am basically sold on it already but I think they might need to up their game a little as far as the presentation of XB2 to the public is concerned.
First, I was underwhelmed by the character design choices, super shonen/manga/Tales of/KH-Nomura, compared to the more serious designs of the two first games that reminded me more of FFT and Ivalice games in general. These really suited the style of the XB series as well as their stories. This generic shonen style with cheap/tacky/horrible giant boob ladies though ? Not so much. They look pretty uninspired and I hope they don't reflect the story.
Then on top of that I have to admit what they've shown looked like it needed more polish technically and they also chose to show the beginning of the game so the combat looked like it lacked depth, diversity, and well a good amount of oomph, for lack of a better word, compared to the 2 first games. At this point in the dev cycle, we had seen Monado arts and crazy mecha enemies for XB and Skells as well as NLA for XBX. In comparison, we know pretty much nothing about XB2 and its background, and certainly nothing that would make me go OMG I need this.
