As you said, I'm sure he has other things on his mind, like being outside and breathing fresh air and the rest, but it does feel like he might have had to sign something that may not have been publicised. Some sort of NDA type thing or media ban.

Either that or he's very carefully weighing what, when and to whom he will be speaking. Being cynical, I assume certain parties will be talking about book deals and things so it's probably complicated.

His silence does feel a bit odd though.
