According to this article (quite reputable site), the first 80 of the 1200 M1117 might arrive in December of 2020.
It looks like they might be replacing the M113, though I have to say I am not sure if that would be wise, or even accurate.
The article also mentions it's quite possible the first of some Bradley M2A2 and AAV7 for the Marines to arrive near that date.
Obviously none of the above have happened yet, so better wait and see.
BTW, I noticed the BMP-3 is still available on the Greek OOB. Unfortunately/fortunately that is probably not going to happen. JFYI just in case you were not aware of it.
