With the construction "This time next week/month/year" etc, we almost always follow it with "I will be", then an adjective or the -ing form of a verb, but not "I will + infinitive".
This time next week, I'll be flying to America.
This time next month, I'll be 45 years old.
This time next year, I'll be running my own business.
This time tomorrow, I'll be on my way to Belgium.
