Slight mis-step if true IMO. Like it or not motion gaming is a legitimate genre now, and it's a family genre.
Consider this:
Wii U comes packed with hardware that covers all gaming genres, except the music/singing genre.
Xbone comes packed with hardware that covers all gaming genres except the music/singing genre.
PS4 comes packed with hardware that does not cover either the motion genre or the music/singing genre.
PS4 has less broad appeal than its competition.
Sure motion gaming isn't going to cause a seismic shift in the market, but broadening your potential customer base by having the family friendly, wholesome face of gaming genre available out of the box with no extra expense required gives you an edge. MS and Nintendo have that edge, PS4 might not.
And this won't make PS4 the cheapest console on the market either, in fact it may only make it the same price as Xbone.
