Moving to new classic series a bit of a revelation

There is a difference between buying/upgradeing and selling that is going from 550 to 300. If I already owned a 552, why worry about 332. It is just wait and see what happens when the 5XX arrives.

Having road plan for a new 500 series above new 300 series doesn’t mean it is yet finished in development - meanwhile there may be stock, including model-specific parts, to shift, so keep selling until parts used up of people stop buying.
