I would have a different answer than the previous posters. In formal English, the number of verbs is probably fixed. That is, the English dictionary has not changed all that much over the last few decades or so. Informal speech, or slang, however, is fluid and can change with the times.

As English continues to globalize, it continues to change. New words are being adopted to English everyday.

They keep coming.
