Too bad for Berdy he's showing better mental strength when his skills are starting to decline.
As for Roger, I agree with
@GameSetAndMath: the fact that he wasn't lights out isn't a bad sign at all, but maybe even good - like he's holding his best for last.
@Shivashish Sarkar, saying Roger has a "decent chance" is the understatement of the year. He is still the clear favorite, and maybe not even by a close margin. It is Cilic, though, who has a decent chance in that it is greater than 0, but far less than even. Maybe 20-30%?
And don't forget that for Cilic to win, he has to play his absolute best AND Roger has to struggle. Roger might be a tad jittery due to the stakes and context, but the fact he won the AO against his nemesis will help calm those nerves and build his confidence.
Of course if Roger loses it will be kind of tragic, as this may be his last shot at a "smooth-sailing" Wimbledon title. Next year Novak could be back in form, and various young players could have taken a step forward, and Roger will be a year older. He really has to win this one, if he wants to get to #8.
