I bought the third edition of Volume 1 in the Tenth Doctor Titan Comics series. I've only read the first edition, even though I've bought the second edition as well - can't say I completed the volume out of love.

I stumbled across this while picking up the latest Eighth Doctor issue. I didn't even know there were plans to do a new series of 4th Doctor comics. Perhaps there is hope now for other Doctors as well.
