my 2 cents,
1/ since for each generation lenght and total user base may not be the same, you should not compare them directly in an absolut way
2/ what you could try :
do a similar analysis for all the console (PS2/xbox/Gc vs ps3/360/wii) by checking their market share % during the same time frame (6 year after launch ?). By using % of total user base, you will ride out generation lenght and total userbase.
This way you will be able to compare % PS2 did 6 year after launch (about) vs what the PS3 is doing right now (same for 360 and wii).
Time to Work !
