I predict that none of those things will happen if the game goes free-to-play. Boundless already has fantastic ways for engaged players to further monetize (e.g., buying cubits for personalization, gleam club for quality of life improvements, and fuel for sovereign/creative worlds). We just need to a) continue to invest in increasing the value and desirability of those things, and b) add a BUNCH of new players.
Statista reported that 91.8 million hours of Minecraft was watched on Twitch in August. I think Boundless is way more interesting to watch than Minecraft.
