If they are talking about a FI replacement for the current PT-425 engine, that's one thing, but if they are thinking about another model, to be priced between the PT-425 and the PT-1430, I don't see it selling that well.
Currently, the 1430 is $6500 more than the 425, but there is a lot of value for the additional money. You get a premium diesel with 30 real horses, as opposed to the phony ratings of the gas engine makers. You also get a lot more tractor. The 1430 weighs almost twice as much as a 425.
If that price gap were narrowed with a new gas powered T8 series offering, I think potential buyers would have a hard time convincing themselves to buy the premium gas powered version, instead of the adequate 425 or the superior 1430.
