Neither party is a clear winner still...
I disagree. As someone who owns both formats (RCA HDV5000 HD-DVD, XBox 360 HD-DVD, Sony PS3 Blu Ray), HD-DVD has lost, it's a matter of when will they surrender.
I would refer you to this article at The Digital Bits, who has finally chosen sides:

In short, only one Hollywood studio supports only HD-DVD (Universal); five support only Blu-Ray (Sony, Fox, Disney, et al). The rest support both, including Warner which is one of Toshiba's staunchest allies. Only Toshiba makes HD-DVD hardware (RCA oem's their player and then there is the XBox 360 add-on). Several manufacturers make Blu-Ray players. HD-DVD releases have slowed to a crawl (the only big recent release is the Matrix boxset, which will come out on Blu-Ray later as well). As someone who rents both HD-DVD and Blu-Ray from Blockbuster, the number of new hit releases on HD-DVD is slowing to a drizzle.
The two formats are identical from the media standpoint if you ignore the physical format differences, with only two exceptions -- (1) the interactivity layer, and (2) an extra level of DRM. They use the same codecs (MPEG2, H.264, VC1, Dolby True HD, etc.).
I hate to see Sony win, because IMO they torpedoed the DVD forum and caused this format war, but it's pretty clear that HD-DVD needs a miracle to win.
And since I won't buy a standard DVD if the HD-DVD or Blu-Ray exists, how else would I play the movie on my laptop when on the road? Do I have to buy two copies?
