Discontinued Razer Goliathus Terra

I was disappointed to learn by a Razer customer service rep that the Goliathus Speed Cosmic isn't the same thing as the Goliathus Speed Terra (not only looks) and that the Terra surface was discontinued. I know several pro gamers who were using it and I think it's sad to discontinue products that players have come to trust. I tried the Cosmic myself and found it different as well. Is there anything closer to the Terra? Could the Razer Gigantus be a good choice?
