When it comes to our friends in Europe, it looks like Resident Evil Revelations 1 & 2 will be eShop-only. Why is that, you ask? Capcom shared a statement with Nintendo Life in which they said a retail release wasn't viable.
Capcom has to take various factors into account when deciding what format to deliver our titles to our fans. These can include but are not limited to overall production costs, manufacturing times, distribution, and first party regulations. In the case of Resident Evil Revelations, we've found that unfortunately it's not viable for Capcom Europe to create a physical version of the title on Nintendo Switch for our territories, however we will be making this available as a digital release.
Make of that what you will, but it sounds like a raw deal to me. At least Resident Evil fans can import the retail copy if they want, since the Switch is region free.
