There might very well be a Honda or a Yamaha out there.
Honda spent close to 5m in engineering with Orbital and Honda has 15+/- patents on engines with Orbitals DI.
At the same time(excluding last fiscal,no info available)Honda stopped the engineering work with Orbital two years ago.
Maybe they did what they wanted to do and are now refining certain parts of the engine on their own,or all the work is just going to collect dust on the shelf.

Don't forget that Synerject could very well be a 200m company in a few years and add 10m(clear profit) to Orbitals bottom line.
As for Polaris they are a couple billion sales company that produces a ton of ATV'S and Snowmobiles.
There is also Bajaj,as slow as they are we still might hit a huge winner with the DI system using CNG as fuel.
