so far May 1st is what I have been hearing as the date that info drops including pre-orders/releae datesYes, it is backward compatible with 1.0 lighthouses. (Conversely, keep in mind that one is NOT able to use the Vive controllers with the Index 2.0 lighthouses). I'm planning on using my Vive lighthouses with the Index and Index controllers, as well.
Anyone have any time guestimate as to when the preorder page will hit? I'd like to get the order in before the site crashes.
