The replacement Tsubasa 17 is on its way now...it will probably be a week or two though till it makes it's way here and through processing to be library-ready...You can put a hold on it if you want and they'll set it aside for you. Hopefully it shouldn't be too long...
As for the Gundam Seed DVDS they had to get withdrawn.

For some reason they just didn't circulate as well...which is a shame becuase I just saw that series not too long ago and it was awesome!!! I loved it! It makes me very sad...ah, well...maybe it was because the packaging wasn't all that attractive or maybe because people are watching their gundam elsewhere (online etc.), but regardless, we had to pull it (sadly) to make room for newer series....I'm keeping the discs though to raffle them off at Animanga sometime.
