Macbook Air M2 16/256 GB

Is it wise to purchase a mba m2 16/256 gb right now for 860USD (1327 AUD)? I really don’t do much on my computer, I’m planning to use it next year mainly for studying for NCLEX exam. Is it better to purchase it now while I’m in AUS during black friday sale or just wait til next year for the release of M4 MBA (I’d srill purchase M2 or M3 for a lower price)? Thanks in advance.
