Etrons will start to develop issues soon in air suspension, that's why I personally shied away after having to deal with my Cayenne's air suspension troubles. Our roads and atmosphere will always have you worrying about that. Also been seeing a lot selling for cheap due to motor/battery issues starting to develop. In terms of A5 and A6 I actually prefer the Sonata 2.5 over the A5 and the N-line over the A6 that are sold here. The high displacement engines just don't match the small turbocharged ones in my opinion (I'm sure many others would disagree).
Unfortunately no news, if you would like a new sedan the N line Sonatas are great. If you'd like to save some money why don't you consider going for a used low milage Sonata 2.5. Resale worries hit them quite bad and they're lovely cars. I love mine to bits and can't fathom them not being more popular. EQCs are available for a steal too but getting rid of them will be a challenge in the future.
