The new card is for Amiga 2000, 3000 and 4000 machines and will provide high resolution DVI-D/HDMI capabilities. And, even more interestingly, it is completely open source.
Hartmann explained further on Hacker News:
The card is available for pre-orders. It costs €189.00 (incl. 19% VAT, plus shipping).All OS friendly Workbench/Intuition GUIs can then be used on a high resolution (up to 1280x720@60hz, 1920x1080@30hz) and color depths of 8 (Palette), 16 or 32 bit. A bunch of open source games like Doom, Abuse, ScummVM have been ported as system friendly applications, too, so these run fine. Old games that bang the hardware still go through the custom chipset of the Amiga and are output through the 15khz RGB connector, not via my card. But I'm currently working on an expansion that scan-doubles and upscales the classic video output, too.
