"Biggest comeback ever" may well just translate to strongest 3rd place finish in a console generation when all is said and done unless either MS or Nintendo jump platforms significantly sooner.
SCE, on the other hand is more or less committed to the PS3 until it turns a decent profit thanks to a start deep in the red due to high R&D, specs and initial production costs.
But who knows? If the PS3 ends up being the last 7th gen console in production and MS and Nintendo move on to the next gen, it may well end up being the best selling console of the 7th gen by merit of simply staying in the game longest.
In all seriousness, will the next generation of consoles be such a significant leap over the current that it demands an immediate console upgrade? Maybe from a user interface, but other than that, any attempts to make specs significantly higher would only result in greater initial losses per unit off debut production models (ie PS3), or a significantly higher initial price per unit (ie PS3) which would only limit the potential initial market.
While it's a lot easier to say this now without sounding irrationally biased, it's not as though the PS3 was ever really in any jeopardy or that SCE was ever on the brink of dropping out of the console market, despite a fair amount of wish fulfillment fantasies that desperately want to see this happen for whatever personal reasons.
Soft support for the platform only continued to grow even as the "PS3 is dOmed" predictions persisted, which in the end, is really what makes or breaks any console platform. Lower prices on hardware only broaden the potential market.
