I am interested in getting the Gateway System, but I need to know if I can connect it to my TV with HDMI or not ?
Yes you most certainly can use HDMI with the Gateway/Portal system. Each Portal has HDMI out.
Have a look here for more details please: Hardware Information - Portal / Gateway (scroll down a bit to see the Portal specs).
The Gateway piece does not connect to a TV (to be clear), but the Portals, yes, they have all the outputs including HDMI, except 1394 and RF (channel 3/4)
