I have had a look at the 2023 campaigns where they regularly offered promotions and discounts for FP4, but FP5 was not annnounced before August.
For August launch, there were ‘leaked’ news two months earlier.
I agree that the vibe is full of expectations and I myself expect them to launch something soon, just am not so sure it will be a new phone (or not just yet).
In other words, I would expect;-) to have some more substantial info going around at least eight weeks before the official launch.
