'Big 4' given top-4 seedings at Wimbledon; Kerber also No. 1

Definitely correct to have Federer in the top 4 seeds despite his current fifth ranking.

Wawrinka perhaps unlucky given that I'd say he's in better form this season than Murray and Djokovic.

Hopefully Federer and Nadal are drawn in opposite halfs. A final between those two would be awesome given how they've both come back big time this season.

Thiem has been playing well on hard and clay but can he translate the form to grass? Raonic has seemed a bit out of sorts, as well as Nishikori who can't seem to find a way to play tennis without injuring himself.
