I literally laughed out loud at this. 

Faulty math me no compute. They must have rounded off a bunch of numbers. As in all of them. 

" However, yesterday a separate insider source told IGN that the next generation Xbox will be “six times as powerful” as its predecessor – the key addition being that this will mean it yields a “20 per cent greater performance than Wii U”.

That unverified calculation, if true, echoes claims from the Develop source who claims the Wii U is far more powerful than current expectations"

What the...? 

Anyway on topic the other rumours didn't rely on an anonymous person who's role whether development or such isn't indicated, unless the person is refferring to the first devkits I doubt it.

:S ... my reaction to the news. As everyone, I'm scratching my head or without reaction, finding it absurd... I'm surprised I had to explain that. :P

Pretty much what I thought.

It just came across as a bit random tbh maybe because it's Arnie who being a mannequin is part of his personality.

"Yesterday, IGN quoted a source as saying Microsoft’s next system will be “six times as powerful” as 360 with performance power 20% greater than that of Wii U."

With no hardware design near completion barring the Wii U, this type of scattershot speculation is practically a given. It's a little disappointing given the way reliable information should be proliferated today; it ain't no game of "telephone" at any rate, but it's also a given that there will probably be a fair amount of misinformation being deliberately leaked and or made up both by the engineers and project managers who know the facts, as well as by those who don't have a clue but firmly believe that any news, even unfounded or completely ficitonal news is a-ok as long as it generates the hits. 

So the "news" we are currently being led to believe is that the Wii U has roughly twice (100% increase) the processing power of the Xbox 360 and that the Xbox 3 will be on par with the upgrade between the GC and the Wii, in this instance, a whopping 120% increase based on the stellar reporting that "the Xbox 3 will have 20% more power than the Wii U" just yesterday, which completely contradicts reports that the Xbox 3 will have 6 times the processing power of the Xbox 360. 

It goes without saying that the 120% number based on Wii U = 2x Xbox360 power + 20% is beyond laughable. 

So what is it? Is the Wii U slightly less (20%) than 6 times the power of the Xbox 360 or is it twice the power of the Xbox 360? 

It will be a lot easier to cut through the guessing once reliable information regarding the specs are released. 

Ugh, why should any one listed to someone who calls themselves Hump Master Flex and sounds like he is MAYBE 16 years old.

Both of these consoles will have custom graphics processors based on commercial graphic card technology.  It is completely impossible to compare their possible performances at this time, because no one but developers with the hardware know their stats.

These speculations are less than useless.

lol it seems as if for some people the rumours are only believable when the wii u is said to be considerably more powerful
i actually remember a few weeks back one of the sources saying it may only be 1.5 times more powerful than the ps3
but whatever we'll just have to wait a few more weeks to see

Hooray for misinformation and stellar internet reporting.
