The folks over at Sony continued to remain indifferent to the matter when asked, citing “We can’t comment on rumors or speculation.” Kotaku has had their fair share of accurate scoops in the past so to hear of a PlayStation 4.5 is certainly interesting. After all, Microsoft has also planned to do something similar down the road, offering incremental add-on upgrades from time to time in order to keep up with the latest in technology, as opposed to waiting for a new generation console after a number of years.
As for the PlayStation 4.5, we do not know whether it will arrive as a purchasable upgrade, or will it be sold as a whole new console. It does not seem, however, that the console will need to be opened up for new parts to be put in, just like what Microsoft thought, but would be adding on new components and parts.
