Michael Pachter has a bit of a spotty track record as far as gaming predictions go, but he gets more right than wrong; at the very least, his predictions are deemed to be accurate enough that his analyses are used to make investments and disinvestments.
For 2015, he predicts that Sony will continue its lead with the PlayStation 4, and that, specifically, their superior lineup of mostly in house exclusives will do it for them.
“Assuming that Xbox One reverts to the $399 price point, I think that Sony first party software will make a real difference in 2015. The company has a phenomenal lineup of exclusives, and they’re spread throughout the year. This should keep interest in the PS4 high, and should allow Sony to extend its lead,” he said.
Personally, I am inclined to agree with him- Sony’s games like Bloodborne, Uncharted 4, and funded ventures like No Man’s Sky, in addition to highly desirable fare like Persona 5, make it the best system to own in 2015 for my money. No exceptions.
