1 architecture (base), multiple machines... Xbox 8 will be one of those machines, this is another one.
Just speculating
This is my assumption as well. It is the only thing that meets the available data, rumors, and news articles with sources from MS. Here is what I posted earlier in the tech thread.
This is all quite fascinating, so I thought I would chime in and try to add a little strategic analysis to the discussion. Fair warning, I am not a technical person. However, I am a strategy professional.
I will take Orbis first.
The latest information and rumors lines up fairly well with Sony’s vision, capabilities, and limitations. The only questionable item is the cost of the memory, which I do believe was raised due to competitive pressure from MS and developer requests.
Durango is far more interesting since there are such wildly divergent rumors/information out there. I will first layout “facts” and assumptions and follow that with analysis/predictions.
Facts:
Powerpoint Leak
MS has publicly discussed the idea of forward compatibility
MS wants/needs to dominate the living room
Apple and Google are the true competitors
Gaming will drive early adoption and provide a differentiator to above competitors
Multiple media outlets have written articles about xbox surface tablets supported by multiple MS sources, see verge article http://www.theverge.com/2012/11/6/3608432/xbox-surface-xbox-tablet-7-inch.
The same sources indicated that the June surface leaks did have the correct specs.
Assumptions:
Initial plans called for at least 680 level performance
Many, if not most, of the rumors with concrete numbers are true, for certain values of true.
Lots of others that I don’t have time to reference.
Analysis/prediction:
1. all software for next box is scalable through forward compatibility
2. There are at least 4 SKUs being prepared
a. Set-top xbox
b. Xbox surface (if the 24th meeting confirms this, then the probability of the rest of this shoots through the roof)
c. Xbox next
d. Xbox Pro/server
3. The leaked powerpoint has most of the major initiatives in it
Description of SKUs
Set-top box – either super-slim 360 soc at 28 nm or some jaguar APU. This is the basic cable box alternative.
Xbox surface – 7 in tablet that plays windows mobile games and can act as a terminal for streamed content / games from xbox next and server. Has jaguar APU
Xbox next – base games machine. Has most of the leaked specs – 1.2 TF GPU, jaguar apu, 8 gb, secret sauce created something roughly equal to Orbis. Target 1080P 30 FPS, high image quality. Can play games and handle multimedia simultaneously, including streaming to 1 surface. May have HW BC initially.
Xbox pro – enhanced xbox with more memory, hardware BC to 360, and 2 GPU units, can play graphically enhanced version of next box games 1080+, 60 FPS, enhanced IQ, and stream to multiple surfaces.
This structure best fits the available data and provides a framework to achieve MS goals for living room dominance. Could they go in another direction? Absolutely, but given the available information, this seems to be the best observation. The meeting the 24th should be very telling.
