Nuendo 6.5?

oh gawd I hate those “car analogies”.
A car is a car, and software is software, people really need to stop with these out of place comparisons.

When did you last get a free “update” for your car?
Can you upgrade your car to the newest model by paying an upgrade fee every two years?

So there, a car is clearly not a software product.

(Well, at least until they start building cars running on Android OS)
