Your missing something very important in that thread. They were not just talking of downgrade. The had basically listed everyone the most consistent specs. Just to back the "most consistent" part a developer here by the name of nylevia basically stated that the range was 150 to 200. 

I honestly don't believe that "downgrade" but the listed specs seem pretty inline with everything observed so far. Nothing was exactly "vague" in this thread if you knew how high tech would work. Don't just ignore thermal designs of a semiconductor! They may even tell which chip is more "powerful". Process nodes evenly matched, a 5 watt gpu isn' going to be beating a 300 watt gpu anytime soon. The dev maybe wrong about the downgrade but most probably are right about the specs! (After all the wii u consumes less than 35 watts!)

No offence but considering that speculation is as common as anything listing that doesn't make them credible as they could have got it by just visiting another thread else where, anyone with some decent knowledge and way of words can come across as an expert on the net using current speculation. It's one reason I stopped paying attetntion to all these rumours, a few years from now we'll probably be hearing different speculation from the same people, all I know is that the U can do games like X which suits me fine as it highlights a big enough leap over the previous gen for me.

The Wii U has more ram, thats it. Everywhere else it is lagging. You obviously do not understand the correlation between semiconductor lithography and power consumption.

Wii U : 40/45 nm & 40 Watts

PS360 Slim Versions: 40/45 nm & ~100 watts

Do the math.

Yes, it is literally impossible that new architectures (HD 40000 vs RadeonX 1800) improve the GPUs´ performance per watt ratio over the span of around 5 years.

...le sigh....

As Wyrdness said, anybody can claim to be a dev and spout the same rumors.  

What we do know is anonymous people say one thing and real developers say something else.  All the numbers in the world don't mean a damn thing if all the numbers are speculation.  Yes, we have the TDP but TDP doesn't tell you the entire story and it's ignorant (in the literal terms, not derogatory) to draw conclusions beyond just that figure.  Especially when they run contrary to what actual developers with actual names are telling us.

It is fine... just the specs are known now... before it was only rumors.

To be fair it is inline with the rumors.
