No. Xenogears and the Xenosaga series (Episode 1 and 3 in particular) have a HUGE fanbase. Many people see those games as having, possibly, the greatest stories you'll find in a game. Xenoblade (judging by the reception from Japan and those who imported it) seems like it will be no different and will have a large following here as well.
