CBR's main page is speculating the TARDIS might be destroyed. Could be interesting to have the Doctor stuck on Earth again. I seem to recall that being a major criticism of RTD's first year is that the entire season was set on Earth (although at different times) or in Earth orbit. It wasn't until season 2 that we got alien worlds (although only two, really).

Think that happened in the books but it eventually regrew itself after a century or so. And of course the Tennant/Smith and Capaldi/Jodie regenerations 'broke' the console room.
