Didn't notice this...
Well... the two main Type-Moon translation projects have been mentioned, but I'll list everything that's been translated (or is being translated) currently:
Tsukihime (Complete) [Visual Novel]
Fate/stay night (In-progress - Fate route complete) [Visual Novel]
Plus-Disc (Complete) [Tsukihime sequel - Fan Disc]
Plus+Disc (Complete) [Tsukihime sequel - Fan-Disc]
Kagetsu Tohya (Complete) [Tsukihime sequel - Fan-Disc]
Melty Blood (Complete) [Tsukihime sequel - Doujinshi Fighting Game]
Melty Blood ReAct (Complete) [Tsukihime sequel - Doujinshi Fighting Game Expansion]
Melty Blood Act Cadenza (In-progress) [Tsukihime sequel - Doujinshi Fighting Game]
Fate/hollow ataraxia (In-progress) [Fate/stay night sequel - Fan-Disc]
Fate/Zero (In-progress) [Fate/stay night prequel - Novel]
Kara no Kyoukai (In-progress) [Novel]
To my knowledge, that's everything. I think there was talk of Act Cadenza Version B getting translated, but I haven't seen any posts about its progress.
On Plus-Disc/Plus+Disc, the difference between the two is that Plus+Disc is a later version, and thus has more content. They're also in slightly different formats... Oh, Plus-Disc runs off the free demo you can download from the official Type-Moon website whereas Plus+Disc runs off the version from Tsukibako (The Tsukihime, Plus+Disc and Kagetsu Tohya pack).
