So, I just thought I'd provide a little more of a demonstration of what I'm talking about, in terms of weakness of the industry right now. I just found a quote on NeoGAF where someone noted the first June after release in the US for each of the consoles back to Gen 6 (the member's name is Mpl90). Here's the numbers:

PS2 - 343,000
Xbox - 265,000 (month after the price drop, from $299 to $199)
Gamecube - 213,000 (month of the price drop, from $199 to $149)

Xbox 360 - 277,000
PS3 - 99,000
Wii - 382,000

PS4 - 269,000
Xbox One - 197,000
Wii U - 42,000

Now, consider these numbers. In Gen 6, Gamecube and Xbox both managed to sell over 200k in June. PS2 nearly made 350k. In Gen 7, Wii easily broke 350k, and 360 did better than PS4 did this year, while PS3 did better than Wii U did last year.

The sum of the three for Gen 6? 821k.
For Gen 7? 758k.
For Gen 8? 498k.

Do you see?

Let's do it a bit differently. Let's ignore the super-popular systems for Gens 6 (PS2) and 7 (Wii), and drop the Wii U from Gen 8. The numbers? 478k, 376k, and 456k. So the best two for Gen 8 didn't even manage to outsell the worst two in Gen 6, and didn't do a whole lot better than the worst two in Gen 7 (despite both systems starting out relatively weak).

Another way to look at it is in terms of comparing them with Gen 6 by company. PS4 is selling noticeably worse than PS2. Xbox One is selling noticeably worse than Xbox (both got a price cut, too). Wii U is selling much worse than Gamecube. Sales in first June don't correlate strongly with LTD sales at the end of a generation, so this isn't a comment on how the generation will go... but using the last two gens as a reference point, the sales right now aren't as hot as they should be.

^considering this gen is a lot more stuck in cross gen, i'd say they are nearly as hot as they could be.

WiiU is not 42K, it's 142K.

Given that VGC always undertracks PS4 by a noticable margin and that it has PS4 at only 4-2k away from 100k , i think its pretty safe to say PS4 didnt drop below 100k.

And given that PS4 has no 'wow' factor like motion controlls and no exlusive big hitters so far, I'd say it's pretty amazing it was ahead of Wii for such a long time

Those numbers are first June for the system. So the Wii U number is for June 2013.

Sorry, I thought it was this June.

The other thing to keep in consideration is that the Wii sold a fairly significant percentage of its overall unit sales off the backs of Wii Sports and Wii Fit.

I don't think it's much of a stretch to say that many of those consoles were purchased by consumers who never bothered to buy any other games before they stopped using their Wii altogether 1-2 years later. 

The PS4 isn't going to score any of those types of sales; it will depend upon overall catalog rather than one or two crossover titles that non-traditional video game consumers will feel compelled to buy. 

While I wouldn't go so far as to say the PS4 will be the Wii of the 8th gen; it's far too early and it simply lacks the widespread appeal of the Wii to the non-traditional extended audience, but barring any major disruptions in the overall gaming market, the PS4 will be the long distance runner to the Wii's sprinter. 

The first Xbox was selling more than the Ps3 and barely less than the 360. I was wondering if someone told at that time that the Ps3 would sell less than the orginal Xbox and the 360 barely more.  Same for the WII VS Ps2 .
