It will probably stay. They redesigned the TARDIS in 2010 because it had been 5 years and time for a change, and the only reason they changed it again this 년 is because they moved from Upper 보트 Studios to Roath Lock and it was cheaper to build a new TARDIS than to 옮기기 the old one.
Basically: it's expensive and there's no reason for it.
I think it will stay the same because the 팬 are still getting used to the new interior, it did not change with the genration of the 9th to the 10th doctor.
