1st or 2nd or 3rd place is not a big deal. The only thing that really matters, is that you are happy with your console system(s).
PS3 can still finish 1st or 2nd place. 360 is destined for 3rd place in 2011.
PS3 may even catch up and over take the Wii in 5 years time. PS3 can last much longer than 10 years and it has the technological advantage over its competitors. When the PS3 prices falls, PS3 sales will increase.
