Very much so. I'm a huge Keaton fan, so as many of his films as can get released I will buy. Personally, outside of the upcoming Keatons and Metropolis, I'm hoping for releases of:
The Black Pirate
The Cabinet of Dr. Caligari
Nosferatu
Of course, one of my favorites is Keaton's Seven Chances, but it probably isn't that high on their list.
