This is another update to the thread and shows sales data until June 29th, one day short of the end of Q2 2019. Once again the PS4 is holding it's own and looks set to defy the popular opinion in the OP poll that the Switch would easily dominate it in 2019.
In 2019 to date -
Nintendo Switch - 6.1 million
Playstation 4 - 5.3 million
This means that the Switch has 53.51% of the 2019 head to head market with the PS4 tracking at 46.49%. I think most will agree that Nintendo has some seriously heavy hitting software to come in the second half of this year but will it be enough to achieve the domination that many expected? Will the Lite be the SKU that gives the Switch the edge going into the 2019 holiday season?
I'd like to hear any thoughts on this and I'll update the thread at the end of September to see if Q3 changed the situation in favour of either console.
