".... i said the Truck will be shown in Dubai in early 2019 "
you repeated statement, in a similar manner several times between Oct & Nov.
Some where in your many posts you clearly mentioned a showing in April, 2019 as I and others picked up on that time frame in our responses to you - we all couldn't be wrong. Don't really recall that a given date stated of April 1 for announcing just the fuel component until today but an announcement of the whole enchilada.
Your today's post seems to strongly suggest your are now "crawfishing". A crawfish is also known as a mud bug in some parts of the US.
