I trust VGChartz, Vita numbers should be anywhere between 15 and 16M.

PSP I remember only once where I've mentioned it (in terms of lifetime sales) and it was way before the announcement of 82.5M, I mention it that it should've reached 82M based on some calculations .. however I don't remember exactly what they were. PS2 for me is anywhere between 158M and 159M+ (under 160M)

Yep all pretty reasonable numbers that should be very close to reality.

JAPAN numbers and charts have been updated with the month of December!

All comparisons and charts have been updated and adjusted with the month of December!

XBOX comparison table was changed with the XB1 numbers (instead of X360) as clearly this is the target for the XBSX now, not the 360 (of course the chart with 360 is still here).
PS4 lifetime numbers were slightly adjusted.

All data now is 100% accurate to VGCharts latest updates!

Some other charts I made recently:

Hmm that will be like a ps2 repeat if PS5 outsells the switch.

All numbers have been updated and adjusted with the month of January!

All numbers have been updated with the month of February!

All JAPAN comparisons have been updated with the month of March! All comparisons have been adjusted too with the latest VGChartz data! New poll was added! Vote now. (results from previous one are in the bottom of the original post).

All of the comparisons including the ones in my previous threads were slightly changed (yes even those from 21 and 22 alongside adjustments there as well), to include new column about the month and the year (weekly ones with week and month). This is mostly because it's way more easier for me to adjust and even change (when needed) comparisons and data that way instead of the old one. The month, the year or the week is now only included in that first column.

Another change is the PS5 japan comparison is now vs the PS3 numbers instead of the PS4 (as the PS5 is performing better than PS4 for now, and of course the target for every console is always to perform better).

The Switch JAPAN comparison may soon (when the DS is passed) be changed to vs Wii+3DS (japan) since this is the next in line for Switch (which is around 37.5M. (the DS one I will still leave here, maybe in a spoiler tab since the post gets very big.

As I have mentioned before I believe the PS5 will outsell the PS4 because the fanbase for playstation always has bought the playstation.
