I think it's an issue that the PS3 didn't completley destory the competition but I don't think it's something that could have been helped each generation is a new race and winning previous generations isn't going to entirely determine your success in later generations history has proven this , also factoring damaging decisions made by Sony such as complex architecture , high price point , not buying exclusives , releasing a whole year after competitor .
I don't see it as much of a big deal that Sony hasn't come in first place it's the nature of the gaming industry that companies loose steam if they're not able to change strategy to adapt to challenging situations . I do see it as a big deal that Sony adapts to their current situation and atempts to maintain profitabiltiy as opposed to marketshare . With the exception Blu-Ray success , HD TV sales the PS3 has been a loss for Sony this generation and I think it's really down to Sony to revise their stratergies for a succesfull PS4.
I still believe however that the PS3 will come in second place and at least break even.
