Hey man it is free, all these guys give their time in a hobby for us, so
it does not take long because there should be no expectations whatsoever!!!Now if you look carefully, they have their plate full at the moment just keeping the existing base of hacked drive functioning, new stuff is only likely to come after. Infact even current flashable hitachi should take a few weeks for iXtreme.
Now if it is urgent, and as per this thread you can send it to be flashed by removing/flashing/resoldering the chip on your drive. You could even from that point buy a nice Samsung in the BST section and use the FW extracted to transfer your key in a it and get everything already available.
ALso in the first two or three pages of this forum you will find
Xecuter X79 Mod for the Hitachi 079, which is another options developping for your v79
