Sony is currently facing a loss in profits in a fee divisions as well as overall, and its future success won't be stopped at all, here's why

1. PS Vita - the vita allows for online sales which generate greater profit margin, and another platform to port games onto, thus adding some revenue but little cost.  Eventually, I think that the vita will rival the 3ds in sales but it will take some time, just like the ps3 was wanting to match the Xbox 

2. Bluray- the ps4 won't be hampered by being so overpriced like the ps3 was, heck the 720 will have the same Bluray reading capability and thus a more similar cost than we had this generation.  But the 720 having Bluray capability means that more blu players are out there, and we will have greater sales for them, increasing blu marketshare.  Also, Microsoft will be paying royalties for the Bluray since its a Sony ip design.

3. Weaker msft and ninty???  -  Microsoft is growing much more slowly than it was 7 or 8 years ago, so they won't beagle to just pour money into projects like they used to which has always been a strength for them.  Nintendo isn't expected to have a great product for next generation either but this is admittedly a lot of speculation on my part.  If anybody knows anything said about how good of a product the wiiU is supposed to be or estimates of future sales have been made, let me know...

4. Super slim ps3- the new upcoming super slim ps3 will have a lower manufacturing cost and be morel pilar in places like Japan that value space, as well as serve as Sony's product for the second and third world for 6 years or more.  This new model will spur greater sales down the line.

Except, the BDA owns the rights to blu-ray and not Sony. And if you were to want to make a blu-ray player and needed the licenses and patents you would actually seek out the BD4C Licensing Group; which consists of Mitsubishi, Thomson, Toshiba and Warner Bros.

Microsoft is also expanding pretty quickly, over the past three or so years they've announced several pieces of technology that they are making themselves. With the company itself increasing it's server software, putting out cellphone OS, building their own tablets, as well as picking up Skype.

Meh, msft has done nothing on phones and I expect the tablet thing to be almost as bleak I mean the market is moving to mobile devices but even if msft gets 20% of that market it will means that there are less users of msft OS, but I'm with you on the skype thing.

Its better than doing nothing. 

I agree, they cant just roll over and play dead but it seems that mediocrity is all msft will ever show us...

I thought Lumia was doing pretty good? Can you update me on how theyre going? I dont follow the mobile/tablet news as much as I used to. 

Your OP is confusing. You say Sony's 'future success' won't be stopped. Well, of course, it won't be stopped, its the future. How can you stop something that hasn't happened yet (?)

Unless your a higher dimentional being that can see every possible future? Duh?

yes BDA owns the trademark to blu-ray but each company holds their own patents for their onw inventions (in blu-ray). BD4C Licnsing Group is just for the patents of these companys and not for all blu-ray patents and since sony was a founding member of BDA and basicly (as far as i know) pushed blu-ray the hardest, i'd figure that they've got some essential patents to blu-ray, wich means every blue-ray disc or player sold also gets sony money.

BD4C: "[...]The group was formed in an effort to offer licnsees an one-stop shopping for essential Blu-ray and DVD patents owned or controlled by the four companied.[...]"
