I am ready to order Model Y LR AWD. However I read that several big improvements are being planned for Model Y in terms of new Battery (4680) and efficiency in rear under chasis which could lead to 5000 to 8000$ price reduction and longer range. Does it make sense to wait for another 6 months to buy the next gen better and cheaper Model Y? Or is it a mirage and we are talking about 1 to 2 years before these benefits are seen?
