Regarding consoles, people say that Sony will make announcements this year and that would be working on the new PlayStation. Are we going to see a new model in some months?

It’s still a big secret, but our Sony PlayStation friends are getting ready. I only can say that we’re focused on the games related E3 event, booked for June. The announcement can take place there or even before, in May.
But are you working on a big reveal or in something complementary?
Probably the first, we plan to release big news for this date, but we have to wait at least until May.
