Will / Won't (predictions)
We often use will / won't + infinitive for future predictions, to say things we think, guess or know about the future. For example: She'll be late. We often use I think / I don't think + will.
Using will about something in the future suggests that you're very confident that it will occur. "We will win this game" is much more definite than "I think we will win this game" or "I'm guessing we will win this game". Isn't it the same in Spanish? Vamos a ganar esto juego. ¿Significa que es cierto? ¿O solo que yo creo que es practicamente cierto?
