From time to time I come across a sentence with to + verb, but with no other verb in it. I see it often in news titles. For example:
Squall, Tina and Lightning to appear in Final Fantasy Explorers
But what does it mean? What is the difference between this form, and that:
Squall, Tina and Lightning are appearing in Final Fantasy Explorers
The first time I saw that, I thought it was a mistake.
