Happy Birthday, Ryng_Tolu! Here's hoping Splatoon brings you an early Christmas present!
My take on PS4/XB1 ratios for November is that the consoles sold in Black Friday week may be dead even. The early Infoscout numbers point to this, they were both mostly available for $299, and consumers don't really seem to care for one or the other that much at Christmas. However, I think the earlier month sales with BlOps3 LE PS4 and more importantly the Vader PS4 with Star Wars fever so high will push PS4 over the top. Also on 3DS, I believe in Wal-Mart. $129 3DSXL (not New variety) will carry the system higher than most predict to possibly ~flat YOY (it's still a declining system, after all).
Also, I'm going to assume that Welfare didn't mean to predict 3DS sales of 4.7m for the month. (~_^) (Edit: See Welfare's comment on it now. I just assumed it was an order of magnitude error and deleted an extra zero to make it 467K.)
