Its gonna sell a bunch more, at least this year.
They have five major pushes, and fairly evenly spread out.
MLB in April/may. Watchdogs in May. The last of us in Summer. Destiny in September. Order 1886 around Holiday 2014 most likely.
Each one of those are system sellers. Huge MLB fanbase, most a lot of which will want to pick up ps4 for it. Watchdogs garnered good press, good pre orders. The last of us, will sell a bunch of ps4's, no reason needed. Destiny, PS4's first BIG shooter and Order, will get a likely holiday push by sony.
Now two of those games are on xbox one as well, but Sony has exclusive rights to Hard bundles on Watchdogs and Destiny. Hard bundles do work, as it was what broke the xbox 360's streak in npd hardware results when gta v ps3 bundle was released.
Now why do I say vs xbox one. Halo can turn the tide, but it is heavily rumoured, and makes sense, that halo is releasing in 2015. Up until then, the only major releases which are system sellers are watchdogs (advantage ps4), Project Spark (Looks cool actually), Destiny(slight advantage to ps4), Assassins creed unity(Usually partners up with sony), Sunset overdrive (MS big holiday game) , The division(Advantage xbox) and Batman Arkham knights(usually partners up with sony w/ exclusive content and bundles) and quantum break(only xbox game im excited about).
From xbox's list, the differentiators are Project spark, sunset overdrive, the division and quantum break. 3 of which are releasing late in the year, 2 of which fit the niche-style gameplay.
So this looks to be a slow year for xbox compared to ps4, so that may explain the price cut (MotherFudging £80 price cut in uk)
Wouldn't be a bad time to announce halo anniversary 2?
