One of those two is a monster but PS4 (outside of having much higher inventory for launch) isn't it. 

Because the console launched? It happened to sell at launch... it was not a ilusion.

The Wii was definitely a monster alright, but the statistics of the decline for the PS4 are not easy to ignore. In fact, if you gave this to a statistician they'd tell you that a bridge is on fire. Its consistent and visible, and you can see that even the front-loaded sales were overcome by the Wii within a few months AND it maintained a much stronger baseline. The Destiny blimp is nothing more than exactly that, a blip.

In fact, since we want to look at this statistically long-term, then the trend would very, very much devalue that huge launch spike and make the PS4 curve project much, much worse than the Wii's almost flat line. The trajectories of these consoles are, given current data, not even remotely similar. In fact, every console this gen has a trajectory right into a shrinking market. (Not to mention that the PS4 has utterly failed in Japan...)

Odd day for me to be on Soundwave's side of the fence but the statistics are impossible to ignore for someone who works with statistics.

BWAHAHA!  So, you're telling me that if the PS4 comes out ahead of the Wii this year (2014 vs 2007), you're just going to find some excuse to downplay it?  I find that pretty sad.

So you are giving me 100% certain PS4 will sell below Wii in it first holiday after launch? Well it can happen and can be more likely than the opposite but this didn't make sure it will happen.

When happen then we can talk about how PS4 lacked behing Wii.

I'm showing facts proving with numbers them... you guys says it will underperforming because guesses that it will sell less than Wii.

Yet it can't even consistently meet a monthly minimum of 250K in North America ... 

I work with statistics and raw experimental data, I never give 100% unless its the latter where I have physical things to present. I give estimations, predictions, and formulae from which conclusions can be drawn and then verified experimentally.

You're not really proving anything at the moment other than the fact that the PS4 launched strong while the Wii performed more consistently... which is their point, actually. They are saying, very specifically, that the strong launch and subsequent inconsistent and sliding month-to-month sales (barring out outlier and Destiny outlier next month) are a very, very bad sign of a front, loaded console that is not actually doing as well as people think it is doing... This is literally impossible to deny as its very much in the numbers you posted.

Trajectories do not paint a good picture. Trajectories can also be wrong... but then normally that isn't the case because a trajectory exists for a reason.

Your own data is especially damning if you compare 2007/2014 only.

You and soundwave should really stop.  You're just making yourself look ridiculous.  You're shifting this way and that to downplay the PS4's success.  YOU made up some fake 250K that a console has to sell, not the industry.  NO ONE but you.  And here's a fact, the 360 couldn't pull off a consistent 250K+ in the US, either.  But guess what?  IT WON THE US!  Just stop while you're behind.
