According to some new financial data shared by CD Projekt on their official forums, half of the The Witcher 3: Wild Hunt's revenue by the end of June 2015 came from digital sales.

Here's how it breaks down according to the studio representative who answered a user's question (thanks to boskee for the translation):

Sales by Platform:

PC - 30%

Consoles - 70%

Physical and Digital Revenue %:

25% - Digital (50% of total revenue)

75% - Retail

Financial data excludes the proceeds from Expansion Passes and pre-orders.

To note, 80% of all marketing costs were covered by the distributors -- Namco Bandai, Warner Bros and partners in other regions.

The reason for digital amassing such a huge chunk of revenue despite the split is due to the majority of PC sales coming from their own platform, GOG.com, meaning 100% returns versus retail which includes manufacturing, distribution and other costs that eat away at profit.
