That's a fair point. But yeah I think from many fans perspective it'd be nice to get one right at the beginning of summer so you can take it on holiday or wear down the pub etc."they must miss out on some serious revenue" - I think it's probably the opposite. They'd miss out to a greater extent if they released all the shirts at the same time because each shirt would "cannibalise" sales of the others.
They want to maximise sales of all 3, so they give each one a window of a few weeks. Their aim is for people to buy the home shirt, then see the away one and think "I wish I'd got that instead!", then do the same when the 3rd kit comes out - a bit of FOMO so they end up buying multiple shirts when maybe they'd only planned to buy one.
If you had 2 or all 3 to choose from in relatively quick succession I imagine they'd lose a good chunk of sales with people only picking their favourite. Of course they could make each sales window longer, and make the most of people going on summer holidays, if they released the home shirt a bit earlier.
Start of June - Home Shirt
Start of July/ Start of August - Away or 3rd in either order
I've oversimplified it of course but that would make the most sense rather than getting one in mid-July and the other two around the actual start of the season.
