This is wonderful news because the ending quite frankly horrified me, and it also was incredibly sad and very abrupt. I can't wait to see what happens in the new manga but...
WHY CAN'T YOU FINISH X CLAMP?! It's been on hiatus for 10 YEARS. It's you MASTERPIECE AND I NEED TO KNOW WHAT THE HELL HAPPENS ESPECIALLY TO SUBARU PRECIOUS BABY I CAN'T EVEN-
Er, moving on.
Ah well, I hope poor Watanuki gets even a remotely happy ending and the ending to this series won't be so crappy like the other. I mean seriously, it's almost as if Clamp said "F*ck you all" and ended it. >_>
Being a fan of this manga, I even seem to like it way more than TRC I can't contain all of my happiness now after reading this! A few more books remain for me to reach the end and now knowing there will be a sequel, I wonder if I will be feeling the same as everyone felt about the ending before this announcement.
I quite liked the ending of xxxHOLiC, though it seems i'm in the minority with that. I'll read the new seires, but frankly i think the time would be better spent on more Drug & Drop and Gate 7. And, like several others have said, it would be nice if they took some of their older series off hiatus like X instead of doing a sequel to one that was already complete.
