InFamous is one of the most heavely bundled games this generation(not that it is a bad thing or anything).  It really doesnt push much more than 1m by it's self so he is right when he says it isn't a system seller.  Most likely it will sell more than previous installments primarily because of a high attach ratio like the original infamous.  After that though the franchise will likely return to its original numbers unless they do a phenomenal job.

Successful Yes System seller No

nope.

WiiU's problem has been primarily because lack of a reason to buy the console.  There hasnt been must have games and unlike Sony and MSFT they cant rely on 3rd party to aid them while they are waiting on their next big first party game.

Sony went through something similar with PS3 in the beginning years though not as severe.  

Not as bad, but yeah. In every generation leading up to this one, there hasn't been a person alive that didn't want the newest system. (citation needed) But despite the pretty good games coming out of next year, a lot of people just aren't that psyched to make the change yet. I know everyone will come around eventually, but right now every person I know that has a PS3 or 360 isn't planning on making the jump any time soon. And that's pretty much never happened before, at least not to this extent.

I believe they will struggle due to how PS360 are currently selling. Current sales are fairly consistent and most multiplat games are coming out for both gens so it really doesn't persuade people to upgrade right away. No one I know is interested in buying one, at least not at launch.

I would say yes both are going to suffer varying degrees of the same thing next year. But I don't expect it to be as bad as the Wii U was, unless the US pile drives the world economy into the ground this week.
Well it will not be immediate, it will take several weeks before the effects of default will be felt. This was according to a economist that was on NPR, the real bad stuff will not happen until the US misses a bond payment because of not being able to borrow, and that will take weeks. The bad news from this is the guy said unlike other times this loomed before this time feels different because there are faction who want to see the US go into default. (i.e. Tea Party)

If the worse is avoided there will be a several month lull after the initial adopters buy their systems since $400 and $500 for a new system seems be out of the comfort range for most average players considering the two studies that have been done on the question on whether people will buy the new systems on/near launch.

In addition to those two points, Game consoles don't seem to be the same "status symbols" they where in 2006. They have been replaced by Tablets and Mobile phones so while it may be true that people are willing to shell out $300+ for the latest tablets, the same is less true about the consoles so holding off will be the cards, especially since most big titles will also be available on the current gen systems, and the "free" to "small investment" to upgrade deal will not be a big draw for these people. (outside of the hardcore initial adoptors.)

Yes it'll happen (like any other console but Wii). But not as bad as Wii U. Because for some reason, even though a lot of third-party games are also coming to PS360, gamers will buy PSBone for those games.

PSBone will sell beacause of brand popularity during the drougth. Wii U sells because of games, since the Nintendo brand is unpopular among gamers (don't know why, but Nintendo is only known because of their handhelds this days, for some reason).

Well PS3 did what 8m in 07? That was with a boost from the late European launch but Wii was stealing all the headlines and 360 was $200 less expensive. This time they'll be the cheaper of the super HD twins and of course have the most positive vibe around them after E3. I also don't think Smash and Mario Kart, as awesome as they're going to be, will steal headlines and mindshare like Wii was this gen so I'll say 10-12m.
