There are standard constructions which allow us to refer in English to future times while specifying a verb. These constructions are understood by all, and work as well as any future tense in any language. To me, that's enough to consider these grammatical conventions to be tenses.
The difficulty of the issue lies in the fact that there actually is a past, and a present, but no one can say for certain there will be a future, or what it will bring when it does arrive.
