Frankly, they'd have to be stupid not to keep some sort of 4" option around. Th only question is whether it'll be a 5s, 5c or something new. I think keeping a discounted 5s around would be a very very powerful addition to the lineup. And then further discounting the 5c.
 
I have to say I do too, it was the perfect size for me as with retina there's more than enough screen space for what I need.

However, we have to accept the decisions of the manufacturers and I think nowadays big is 'cool' and sells phones.

I agree, I was simply replying to the implied suggestion that those of us who want smaller phones, will prefer the bigger one once apple release it. If apple released a 3.5 inch phone with the same spec as the flagship phone, like they do with the retina iPad mini, I'd buy it in a heartbeat.
