I'm familiar with MTH's PS-1 and PS-2, given clinics on TMCC and spent a week evaluating Lionel Legacy for a local shop
Opinion: The combination of S-Helpers locos and MTH's PS-3 DCC/DCS/Sound electronics (not to mention the track and freight car offerings) will cause Flionel blow-out sales, and Lionel will make a partial S gauge reteat.
What say you?
