AMuS with a very doom and gloom outlook on Mercedes

Seems like there is quite a bit focus on the front wing design, in particular
" . . . it came out that Ferrari is currently two tenths ahead of Red Bull Honda and five to eight tenths ahead of Mercedes in all projections."
"Mercedes has already pushed Ferrari into the role of favourite. "Ferrari is the clear favourite at the moment. We have to catch up," stated team boss Toto Wolff. The technicians are arguing about how much. "At least half a second, maybe even more." Up to 0.8 seconds were heard from the pessimists. Valtteri Bottas reported from the cockpit: "At the low temperatures we had trouble bringing the tyres into her window. The balance is on a knife's edge. We're behind, but it doesn't feel like something fundamental is wrong either."
"Mercedes uses a front wing concept that is contrary to that of Ferrari. The flaps are flatter on the inside than on the outside. In addition, the end plates point inwards, which is not to be seen in any other car. Ferrari does it the other way round. Flaps higher inside than outside, end plates bent outwards. All bad air should pass the outside of the car as before. With the Mercedes solution, you have to live with swirling air inside the wheels and catch it again further back with a complex construction of baffles. The fact that Red Bull drives a similar type of wing is not a sedative pill. The rest of the RB15 is completely different from the Mercedes. Strongly set with a nostril that relieves the middle part of the front wing."
"Red Bull technical director Adrian Newey gives a little insight into the aerodynamics: "You have to decide between the two wing concepts. There is no interim solution. We could switch to the Ferrari wing without any major modifications, if necessary. Mercedes would have more problems there. You would have to change basic things on the car." The Mercedes engineers admit that the Ferrari concept is already being tested in the simulations. "It would be negligent if we didn't. Nevertheless, we must not panic now and must sound out whether we can make progress on our way." The major aero upgrade for the second week of testing of course still sticks to the old values."
