is it normal for my boyfriend to say things like this early on??

my boyfriend is amazing and I like him a ton. we started dating in June and he's already started to say things like "you're going to be my wife" "love that I'm gonna be your last first date" "if we get married I'm saying (x) during my speech". he goes to a military academy, graduates in 2 1/2 years and has alluded multiple times to wanting to propose to me right before or after he graduates. so far I could def see him being hubby material but obvi we need to be together for longer to really decide. but if he's saying these things this early on does that mean he's dead serious about us??
