There is no R1 release yet, so consumers haven't seen any dub. All orders for Gurren Lagann are back-ordered and have been since 26Feb08.
No word or news from ADV as usual
The same goes for Kanon volume 3 (back-ordered since street date or March 4). And volume 2 is back-ordered again.
Interestingly, DVDpacific is taking orders for volume 4 of Kanon with a street date of 13May08.
Needless to say, the silence does wonders for ADV's credibility ...
