I think the chance of that is slim. PS2 was discontinued after a 13 year run, just 3 years before the PS3 was. Will probably beat Gameboy sales, but reaching Nintendo DS or PS2 levels would be difficult. We still have this holiday season to account for but as it stands, it is only two thirds of the way there. I see it ending up as the 3rd best selling console of all time which would be a good success.With how well the PS4 is still selling Sony's not going to stop until it becomes the highest selling console of all time. Or, at the very least, gets much closer to PS2 numbers. News about how good the system is selling and it moving up the charts is good for them and will still be good when the PS5 launches as it gives their brand an image of strength.
I see it being $500 with a $400 option.
