New DVD box set got announced by BBC: Regeneration.
It's apparently a coffee-table style release, and 6 discs, featuring the first 11* regenerations. The stories included are: The Tenth Planet**, The War Games, Planet of the Spiders, Logopolis, The Caves of Androzanni, Time and the Rani, Doctor Who: The Moving, Bad Wolf/Parting of the Ways, and The End of Time.
(*I say "first 11" because there are hints that this season or the anniversary special may end with a regeneration.)
(**This is the newly animation-enhanced Tenth Planet, which hasn't been released to DVD before.)
It's listed on Amazon UK as £43.25, and it's not on Amazon US, so, at current, it looks like a UK-only release.
