"Based on the manual, it looks like SPIKE 2 already uses HDMI between the CPU node and LCD. Assuming they're not using some absurd display mode while simultaneously failing to send an EDID from the LCD, odds are pretty good that any HDMI capture device with pass-through could be used on existing games.

edit: On second look, that appears to be for the mini-lcd using HDMI (Looking at the Star Wars manual), with the LCD using a 34-pin cable." From Jared B on Tilt

"I was bummed when I found out Stern went the LVDS route instead of HDMI. Assumed we'd have an easy hookup for all lcd games. I've been on the lookout for LVDS->HDMI devices ever since but they don't exist. LVDS->DVI exists, which may be converted to HDMI or may not. Don't have a new Stern to test with." From Karl Deangelo on Tilt

So far it seems like a no go to share or out put the main display on the new Stern LCD's with out finding adapters and such.
