Three films by Chytilova are scheduled:
"Ovoce stromu rajskych jime" in April
"Sedmikrasky" in May
"Vlci bouda" later in the year
All by Bonton, so I don't know about subtitles.
Also, the releases of "O slavnosti a hostech" and "Vojtech, receny sirotek" have been delayed, because the respective directors weren't happy with the transfers.
The rest of the apparently to be released titles by Bonton have been announced.
3 by Kachyna:
Noc nevesty (The Holy Night)
Kocár do Vídne (Coach to Vienna)
At' zije Republika (Long Live the Republic!)
another one by Hynek Bocan:
Pasták (it seems this wasn't released until after 89)
another one by Masa:
Hotel pro cizince (Hotel for Strangers)
another one by Schorm:
Den sedmý, osmá noc (Seventh Day, Eighth Night)
If all of these will be released, then this is a year I can't wait for. =D>
Some more titles have been announced:
by Vlacil:
Dym bramborove nate (1976) (Smoke on the Potato Fields)
Marketa Lazarova (1967) (seems like Second Run releasing this pushed Bonton to release many, many films

)
Stiny horkeho leta (1977) (Shadows of the Hot Summer)
Mag (1987) (Magician)
Stin kapradiny (1984) (Shadows of Fern)
other:
Signum Laudis (Martin Holly, 1980) supposedly his best
Tajemstvi oceloveho mesta (The Secret of Steel City) (Ludvik Raza, 1979) a Sci-Fi/Adventure
Bozska Ema (Heavenly Emma) (Jiri Krejcik, 1979)
Zanik samoty Berhof (End of the Lonely Farm Berghof) (Jiri Svoboda, 1983)
Pesti ve tme (Fists in the Night) (Jaroslav Soukup, 1986)
Kinoautomat: Clovek a jeho dum (A Man and his House) (various, among others Pavel Juracek, 1966)
And some others, that I doubt are of interest for non-Czechs

. This year could be even better than I expected...and more expensive

.
It seems that
this shop still sells "Obrazy stareho sveta", I have just ordered some other DVDs from them, so if there is interest I can comment on my experience.
It seems however that their site isn't working in English.
I've bought some Czech DVDs when I was in Prague the last few days, and the following don't have English subs:
Nikdo se nebude smat (Bocan)
Obcan Vaclav Havel jede na dovolenou (Novak brothers) (a new doc, my cousin told me it's very good)
Fararuv Konec (Schorm) (I've only watched a couple of seconds, but the quality doesn't seem to be optimal, that is not too sharp)
Navrat ztraceneho syna (Schorm)
Lasky mezi kapkami deste (Kachyna)
Udoli vcel (Vlacil) (but the print looks really great)
All of the Slovak films of the 70s have English subs, plus small booklet with critical analysis of the film and other info, but these are only in Slovak. The original poster is also printed in the booklet. I strongly recommend to buy some, they are a real bargain for the price, even with shipping.
