So I bought the MK3 when it was new. I then upgraded it to MK3S+ when it came out.

Can my printer, that was originally the MK3, but is now upgraded to MK3S+ be upgraded to MK4?

Yes, they've got you covered.

Original Prusa i3 MK3/S/+ to MK3.9 upgrade kit -- $499

According to the blog posted here it's possible for upgrade all the way from the MK1 to the MK4.

I literally just bought an MK3S+ a few days ago... I feel like I should return it and buy the MK4? It's the same price and things like Wi-Fi and faster speeds are HUGE differences for being the SAME price... I really feel they should have hinted/said something when I was buying mine. Like Warhammer 9th edition rule book and then they just slap out 10th edition!

If I were you and had the option of returning, then I absolutely would do that and grab the MK4.

I confirm. My mk3s+ was originally an mk3 and can be upgraded to mk4 (I asked on prusa live chat before purchasing the upgrade)
