The caveat in reference to PS4 vs PS3 is that the PS3 couldn't be front loaded because the price was so damn high. Therefore, its really hard to say. Will the more affordable entry level lead to more front loaded sales for the PS4? Well hell yes as it is the fastest selling console of all time. So PS4 is either front loaded to the max or its the PS2 reborn...(which, for the record wasn't front loaded but rather a freak of nature unmitigated success)
Coordinately is difficult to tell for the Xbox One vs the Xbox 360. The Xbox One is selling faster than the Xbox 360 in the US and UK... not so much in Japan, and its in new markets like China. The US sales will be more front loaded because the 360 took a while to really catch on. In Japan, its dead, and China is something they can work on with more strategic pricing and with the blessing of the Chinese government....
