Yes you are being cynical - what they write is:
> The current UI will remain available for at least two years, and we’re not going to remove it until we’ve seen that the vast majority of our users have successfully made the switch to the new UI.
this sounds like you have to actively switch to the new UI if you already have an older version installed, and that they will be monitoring how many users have made the switch. Only after the "vast majority" (>80% ?) have switched will they "shove it down the throat" of the other 20%. Well, let's see how this promise will hold up...
