If we talk about videogames the greatest comeback had Nintendo with Wii coming from GC. Also after all the doom and gloom about 3DS in its first year they had a bigger comeback, it already outsold PS3 in Japan and in 2 years it already sold nearly half of what PS3 did in 7 years. So I disagree, especially considering that 3rd parties heavily supported the PS3 from the get go and got saved by X360 beeing its "twin" if not the software situation would have looked different in the first years.
