No need to apologize, and for me you were within limits but for one point that you got modded for.
Regarding your point, yep PS4 outshipped but quite probably sold less than Wii. We just need to be carefull on wording and maybe the arguments used (because there would be no way for Wii to be ahead with 9 months and passed in the next month when it have actively been closing shipment and sales gap). (Sorry for adding more Cone)
Wellcome to the site and don't worry yourself too much.
