Can Nintendo catch Sony?

[Oyvoyvoyv]

Isn't a more fair comparison the sales after Sony joined, including everything?

Sony:

PSX: 102M
Ps2: 117M
PsP: 34M
Ps3: 12M
Total: 267M gamig machines sold.

Nintendo:

N64: 33M
GC: 21M
GBA: 79M
DS: 72M
Wii: 25M
GBC: 45M (calculation: Total Gameboy+GBC sales - 119M. Total GB sales before launch of GB - according to hardware shipements - 65M. GB also sold a few more copies, so about 50M, not 53. I say 45M to be on the certain side. )

Total: 280M

It looks to me like that due to this gen total Nintendo sales from after PS launch are higher than Sony's total.

But what is needed for it to have a higher average? I'll do through all time here, as that is what is fair.

Sales LTD:

Notes: I chose not to count VB as we do not have its numbers, I only used "succesfull" gaming machines from both sides. GBC and GB are counted as separete machines

Nintendo total: 462M
Nintendo total machines: 9
Nintendo average: 51.33M

Sony total: 267M.
Sony number of machines: 4
Sony average: 66.75M

Total numbers of both before this gen:

Nintendo: 365M
Average: 52.14M

Sony: 219M
Average: 109.5M

If PsP sells 60M, and Ps3 sells 70M, Sony will average 87.25M
If Wii sells 100M and DS sells 100M, Nintendo will average 62.77M

Wii + DS needs to sell 420M combined to average more than Sony. If PsP + Ps3 manages 130M combined that is.

If Wii + DS manages 300M, the average of Nintendo will be 76.111

Then Ps3 + PsP has to manage only 75M combined to beat the average.

So overall:

Nintendo has total lifetime sales.
Nintendo has total sales after PS launch.

Sony has highest average pr gaming machine, and is likely to maintain it.
