Typically after a while, MSRP prioces go down on the technology you buy, for the Playstation 5 that's different, as global prices are rising by up to 5%. 

Sony has revealed that the PlayStation 5's pricing will rise. Almost every region outside of the United States is affected. Because of the strong US dollar, the US was probably spared. Sony attributes the price rise to the general "difficult economic circumstances" or, more clearly, to excessive inflation. The price hike appears to be immediate. The price of the PlayStation 5 Digital Edition, in particular, has risen from EUR 399.99 to EUR 449.99 here in the EU. If you wish to use the edition with an optical drive, the price has increased to 549.99 euros from 499.99 euros. The PlayStation 5 is now 50 euros more expensive than its immediate competitor, the Xbox Series X|S.

It is currently unknown whether Microsoft would follow suit and raise the price of their Xbox consoles. However, Sony's action will probably be leveraged for commercial purposes. The Xbox Series X has more power than the PlayStation 5, but it is now 50 euros less expensive. Because Sony outsells Microsoft in terms of sales, you might see potential there.

Sony Increases prices of PlayStation 5: in the EU a 50-euro price hike has been announced.
