Digital Extremes has mentioned that Soulframe's post-launch support and content will be similar to how they handled it for Warframe.

Digital Extremes' new Warframe follow-up Soulframe is already in great shape to be a hit on Switch 2, but you play it on your Steam Deck right now.
Soulframe: "Choose to join us and make your mark on Alca to get instant access to Preludes, as well as Wyld Pacts, Armour, and Weapons to aid you on your journey.
Fey blood, steel, and soil entwine anew. Come, Envoy. Step deeper into the Wylds."

Digital Extremes has opened up Soulframe Preludes to public access for everyone who signs up by July 20 at 11:59 PM Eastern Time.
Looks like a great chance to experience Soulframe early love that they're opening Preludes to everyone! Curious to see how it compares to Warframe.
