So Id have to spend more money eitherr renting or buying a Bluray, than what I'm currently doing without the need of a  shop? Without the need to store films? 
Also lately Zunes films have been getting exclusive content like certain Makings, deleted scenes Etc. It tells you on Zune MArketplace when a film has exclusive Zune bonus features not found on the DVD or Bluray. 

Going from the future of tecnology to yesterdays Disc format is backwards. The future will be eavily streaming and downloading, its just a matter of time. So yes Id be going backwards. As I hhave adopted tommorrow early. :)

Good argument, however DVD is still alive and well.

While I believe BluRay will inevitably over take DVD, by the time it does Digital Distribution in films will be far higher. In fact digital distribution and streaming is already taking out a lot of the movie retailers. I have heard personally from the manager at my local FutureShop that their sales of physical media are dropping almost every month except the winter months.

NetFlix and such seem to be where movies are going. Unlike games you don't need to have a massive hard drive and my sister can play HD Netflix films with DSL. Yes having BluRay would open them up to some consumers. But not as many as you'd think DVD remains the primary format and even with HD will likely remain in power another 2-3 years before BluRay fully replaces it. By the time BluRay has fully replaced it as the physical format the streaming and DD film industry will be far larger as well.

So when would BluRay actually be beneficial? About 2-3 years into the Nex-box's life span. However as mentioned by the time it over takes DVD , DD in film will be big enough to compensate for the loss.

As for Microsoft's intent to crush Sony. This is based on many factors including the fact my Uncle on my American side works for Microsoft in  Redmond and used to be at their Seattle office. He told me years ago when DreamCast got Microsoft's operating system that Microsoft was going to enter the industry. He said Microsoft saw Sony as a direct threat to PC and that Microsoft thought Sony was planning to go after them. Xbox apparently was a three phase plan executed to prevent Sony from entering the PC industry.

Now would Microsoft support Sony Pictures? I don't know I have never talked to a Microsoft employee about Sony pictures. But being a division of Sony I would conclude that Microsoft probably would like to avoid giving them money if at all possible. As I said DVD was already a big move and at the time it was necessary but this new generation it might not be.

Also Microsoft has undoubtedly been watching Nintendo. Nintendo proved with Wii you didn't need a physical film format to succeed. In fact NetFlix was most successful on Wii for a while. I have no doubt that Microsoft has taken notes and this leads even further in the direction away from BluRay.

I honestly think Microsoft will have its own disk format to reveal. It may be very similar to a BluRay disk but it will be the primary format for games on Nex-Box. No I don't think they will try to make it a movie format that war is over, but look at Nintendo's success with its own formats in the past.

as you can see Blu-ray is at least as important as digital right now. In Europe the picture is much better for Blu-ray

If they are developing a new medium, it'd be pretty stupid of them to put it in their next system. As expensive as the PS3 debuted at, they shouldn't be putting a new medium (from the sounds of it) in their next system unless they want the price to be sky high again like this gen. Isn't there Blu-ray discs now that are 50-100GB single layer now?

Possible if they want to wait another 4 years and push 4K video I guess, but considering the slow uptake of Blu-Ray and the lack of 4K content plus the added cost I doubt they will go that route next gen. Likely they will just go for quad layer Blu-Ray 1.5 with 33GB layers. There is usally a ~5 year gap between unvailing  and public adoption of new disc formats, CD unvailed 1976 publically available 1982, DVD unvailed (took a long time for the spec to be finalised was first demonstrated back in 1993 as 2 sperate formats) 1995 (first released as a product 1996 in Japan) only really became viable late 1997 when it was propally launched in the USA, Blu-Ray unvailed 2000 spec finalised 2005. Blu-violet cassed discs don't even have a official name yet.

But this isnt a new format,  its essentially Blu-ray 2.0.  BTW Blu-rays use a Blue-Violet laser, in fact the new laser and Blu-rays laser are the same size wavelength, they are just doing different things with it to increase storage.

Plus 33GB layers were announced to be implemented almost 2 years ago, yet they still have not made it to production.  Mainly due to high failure rates in the recording process.  They cannot be relied on.  And all multi-layered discs beyong 2 layers to date have stayed in concept/experimental stage.  Sure it would be nice if Sony's 8 layer or Pioneer's 16 layer discs would be put to good use. But those will never go full production.
