I'm 99% sure that the Switch will release for 330$ here in Canada. I have to major reasons why:
A notable source claimed the Switch price will be 250$USD. That converts to about 331$CAD which would most likely be rounde down to 330$.
That Toys R Us leak fits right into this! The Toys R Us website also said (and this is months ago) that the Switch will be 330$CAD.
What do you think of this, Canadians?
