We’ve got another five days before TiVo makes their big announcement, but it appears that the TiVo Premiere leaks aren’t dying down between now and then. In fact, the Premiere DVR has shown up in Best Buy systems noting availability on March 27th for $299, with a Premiere XL version selling for $499 on the same date. From the looks of things, the Premiere will rock a 320GB hard drive, while the XL will have a full 1TB.

That’s all we have to go on for now, but this is certainly not enough to live up to the hype that TiVo is building around this announcement, what with their whole “Inventing the DVR was just a warmup” stance. We’ll see in a few days.
