Generally, we'd say it's hard to tell what TiVo has up its sleeve with this newfangled "Hawk" software, but given that we already took a peek at what's potentially the next big TiVo interface late last month, we can't help but think the two are related. TiVo has been sending out solicitation e-mails to select Series3 / TiVo HD owners in order to enlist them in a beta program to test out a software release slated for launch sometime this fall. Users are being asked to deal with a few quirks and report them in a timely fashion, and they're promised a small parting gift for their participation. Of note, "Hawk" won't work with Series1 / Series2 boxes, and while "fall" is definitely mentioned, so is the word "December." Meaning? Don't get your hopes up that this release will be headed down the pipes in gold fashion anytime soon.
