this has nothing to do with ps3 hardware sales though.

It makes sense given the announcements. HD DVD is done.

nor does it have anything to do with Christmas.

Ivader did you even read the OP?

On topic:

First time I said it: "Bluray is the winning HD format." 

go sony

For those that don't like pie charts:

Here's how the January Week 1 unit sales looked for each format (week ending 1/5)...

Blu-ray Disc - 15,257 units
HD-DVD - 14,558 units

That was prior to the Warner announcement, which came on 1/4. Now here's how the January Week 2 unit sales data for each format looked AFTER the announcement (for the week ending 1/12)...

Blu-ray Disc - 21,770 units
HD-DVD - 1,758 units

wooow that much :OOOO  sales are pretty low if you ask me

even the psp sells more

uhh .. ouch 14,558 -> 1,758 that's a reduction by ~88%

well this week will be better for the HD DVD , for Toshiba decreased prices

It would be interesting to compare those numbers with Marketplace/iTunes (does it have movies yet?) numbers.

 Not really, Betamax was better then VHS if you look at quality, HD-DVD is worse then Blu-ray in quality so they are not exactly alike, good to see that Blu-ray is going strong though, I think it's all because Blu-ray sounds so much cooler then HD-DVD..

Yowsa, that looks very grim for HD-DVD. Let's see an end to this folly now and get one definate format in our living rooms.
