Are 5" phones here to stay?

I don't know if you noticed, but lately all the major handset makers (except for Apple of course) have chosen 5.0" screens for their latest and greatest phones:

- Samsung Galaxy S5
- LG Nexus 5
- Nokia Lumia 930
- Sony Xperia Z2
- HTC One (M8)

I think manufacturers choose this size, because they can fit a 1080p screen on there, and because of the bigger is better marketing. It is also the maximum size of a phone without making it too big in my opinion, even though for me 4.5" is still the ideal size.

What do you guys think? Is 5.0" here to stay? What do think is the perfect size for a screen?
