No, of course you don't. Why would you want to wait longer? My question is more along the lines of...do you want Yu and his team to have all the time they need to make exactly what they want to make?
At this point, given what they have said, etc, it seems like they have all the tools ready and are just now starting to put it all together. One year does not sound like enough time to me.
I'm sure Yu will delay the game if he feels like he has to...and I'm 100% ok with that. I just hope that people are as well and we don't have a mass of disappointed fans screaming and yelling.
