If you have not heard here is the official announcement of the MP20.

EcoTech Marine, the company that revolutionized coral aquarium propeller pumps with the VorTech MP40w, previewed its newest pump, created for smaller reef aquariums, at Marine Aquarium Expo (MAX) on April 5th in Costa Mesa, CA.
 
The VorTech MP20, available this summer, is ideally suited for aquariums smaller than 70 gallons. With its patent pending VorTech technology, the MP20 produces unmatched broad yet gentle flow while placing the motor outside the tank˜preserving the beauty of your aquarium and enhancing the health of your tank‚s ecosystem. With all the electrical components outside the aquarium and a variety of easy-to-program modes, the VorTech is the safest, most versatile pump on the market.
 
„The MP20 will enable an entirely new segment of the market to experience the technological superiority of the Vortech system,‰ says Tim Marks, EcoTech director of production. „The attendees at MAX were psyched to learn about the MP20. They were attracted to our booth by the innovative design of the VorTech and blown away by its capabilities.‰
