Devil May Cry 5 looks like it won't have any DLC, aside from the Bloody Palace and what's inside the Deluxe Edition. The Bloody Palace launches in April and will be free. 

Responding to a question on Twitter, producer Mark Walker confirmed that the aforementioned survival mode would be the extent of the action game's post-launch offerings, though previous there'd been mention of vague DLC plans.
