Sony should not focus on power next gen. When they did focus on power with the PS3, it only gave them a minuscule advantage over the 360, and resulted in an extremely expensive console. You seem to have forgotten about how poorly the PS3 did during the first half of the generation. Either that  or you're posting from a fans perspective rather than a business perspective, which it seems you are. Sony needs to go back to their PS1/PS2 strategy and ditch the focus on power altogether imo.

Yes, Sony said they've never been first or the cheapest, but so what? First of all, they didn't even make a claim, they just noted a trend with their hardware. Second of all, even if they made a claim, that means nothing. Remember when they called the Wii a fad? Yeah....Third of all, they can still release a PS4 this year at >$300 and they wouldn't be first or the cheapest. This quote doesn't support your argument at all.

I really don't know how Sony lost since they sold close to 600,000 consoles last week and Wii bately managed to sell 200,000, and that was a normal week at the end of this gen.

OP. I hope you're right. I fear you're wrong.

Ideal for sony would be to release the PS4 only once it has 10X the power of the last gen. Releasing a console just 2-4 times as powerful might appear indistinguishable to the 'layperson' consumer - thus go unnoticed. In that event, it would be lacking the next-gen buzz or vibe that everyone gets so excited about.  

Oh, they might announce it at E3 this year just to stoke the fires, but even if they're following a schedule like Nintendo's with  Wii U, it still wouldn't be coming out 'til Holiday 2014.

And you're really putting too much emphasis on the importance of a year's head start.  Just look at the current gen.  Playstation 3 launched one year later and at a price tag of $200 more than the 360, yet they're still going to pass 360 when everything is over and done with.  This time IF 360 manages to get theirs out in 2013 the Playstation would still be launching only a year later and more than likely at no more than at a $100.00 higher price tag.

Now would it really be that disastrous for Sony to release a year later?  Where would it really hurt them?  Well, it would hurt them in America, but as demonstrated this gen, that's really not going to hurt them that much since they could still beat the 360's successor with strong sales in the European and Japanese marketplace.  PS3 will continue to dominate in Europe 'til the release of PS4 whenever that is and Microsoft's consoles will never catch on in Japan.

Really, the smartest move Sony can make to keep their old fans and to attract new ones ( since their games lineup is not as casual friendly as Nintendo's) is to release another State of the Art Console with a price point that is initially more attractive than the PS3's was at launch.

An honestly priced (ie. that they're not losing on and that is as full of the greatest tech that can be bought for the price at the time) $500 console released Holiday 2014 is their best bet.
