Prediction: 80% of Driveclub's sales will be Digital

[Qwark]

I hope it will be since, the game has around 100 k physical pre orders in the US when it launches.
(By this logic this means 1 million units sold on launchday in the US 100K physical +900K digital)
Racing games always sell good in Europe so Europe will also have 100k physical pre orders.
(Another million units sold)
Japan will have 50k pre orders, (450k digital) so using your theory that would mean the game is set to sell more then 2.5 million units in October.

Back to reality it will probably not even sell half of that in October. So a 60 Physical 40 Digital would seem more likely. That still means the combined sales will surpass a million units.
