If you are happy with the aircraft and pay, go for it. Forget about the part that says: "they are planning to move on to the next level of aircraft after 3 years"
If you are there after three years when they "move on to the next level of aircraft" then you dont need to know about it now. Consider it as one of the instructions the judge gives to the jury to ignore certain evidence.
