Some PS4 Vs. PS2, Wii U Vs. GCN, XB1 Vs. XB, etc. Sales Comparisions

[Soundwave]

I would say as another take away, it's unlikely I think the PS4 will outsell the PS2's second year, ditto for Wii U's third year over GCN's, and virtually impossible for the 3DS to match the GBA. XBox One over XBox might be doable though.
