I think the X-staff is running out of ideas that don't involve the X-Men being attacked at home. This decade alone, the mansion was attacked by Cassandra Nova, U-Men, students hopped up on a sentient drug, Xorn, Ord, Danger, Cassandra Nova again, the Brotherhood, Apocalypse, the Purifiers, the ONE, Predator X, and Bishop.
Then when the X-Men moved to San Francisco, Graymalkin Industries was attacked by the Sisterhood (who then took the fight to the old mansion again) and the US government.
Now they're on Utopia, which was attacked by the Avengerbolts within 5 minutes of arrival. It's already being likened to Genosha, which was blown up. I give it another year (maybe 2, but that's pushing it) before Utopia becomes unlivable and the X-Men are forced to relocate.
