How many more expansions?

As the title asks, how many more expansions would you like Root to get? I'm actually starting to think this might never end and every 2 to 4 years we might get new factions but at the same time I wish for it to stop with a new expansion after Homeland, get a big box and be done with my huge Root collection. I think the new optional thinner player boards are an indicator for things to come since the thicker boards made up a third of the weight and took half the space in a box but we'll see.
