Also interesting that PS4 comes with a Blu-Ray player, 500gb hard drive and is 5x more powerful.
But lets only look at PS4 disadvantages.
You think that, in 2015, people are still buying consoles to watch movies? But that’s besides the point. Do you think the PS4 would have sold the same if it released at $299?
Do people buy PS4 specifically to watch movies? NO
Does the ability to watch movies add value to PS4? YES
If PS4 launched at $299 it very well could have sold higher but you also have to take into consideration the other factors that could impact it.
1. Assuming it has the same specs, PS4 would have been sold at a huge loss which could have negatively impacted the amount Sony could spend on game development, advertising, securing exclusive marketing/bundles/content etc which could in turn impact sales.
2. Assuming Sony didnt sell it at a huge loss at $299 than PS4 would have been a completely different device with lower specs that runs multiplat titles worse than XBO which impacts sales among the people who care about power/performance in the US.
We have no clue what PS4 sales would be like in this hypothetical situation, we can only discuss sales that we know.
