Where did they say they are looking to make it compatible? I haven't found a source saying that, only that the current base station system will not work with the steam frame. (expected because its inside-out tracking)
I never said they won't support them (I assume you mean driver/software updates), I said they are abandoning that ecosystem, which they are. They've stopped manufacturing base stations, the old index headset and the old index controllers, none of which has a direct replacement by this announcement.
@NoosphereVR The way they talked about the lighthouse ecosystem in their interview gave the vibe of we want to forget we created this. It's a shame, I wish they would of kept it around as a professional/enthusiasts line of products.
