Cut and pasted from Chris's post:
We already have considerable time and resources invested in our next 50cc release (the first plane that will be built in Malaysia) and it will probably be available before the Yak is. The Yak is but one of many designs we intend to produce and the new 50cc release will certainly perform every bit as well as the Yak.
Sounds to me it will be produced, however there are designs in front of it.
