Next year Ukraine could get more Leo A4 from Poland.
Late May, early June we will start getting M1A1 from US and we should have all 116 late this year or early 2024.
Also we will have 28 K2 tanks in 2023 with 56 more to be delivered in 2024.
That is over 150 tanks and it should free rest of the PT91 or some of the Leopards to deliver to Ukraine
As Poland

has M1A2's and K2's arrive, they'll divest their PT-91's and Leopard 2's entirely. The former prior to the latter, but all of them inevitably. Their T-72's are basically all gone at this point.
Late 2023 / early 2024 deliveries of Leopard 2's will like look something like the following....
14-20 2A4 from Poland
14-20 2A4 from Germany
14 2A4 from Netherlands

and Denmark

10-14 2A4 from Spain
20-30 2A4 from German industry
I don't expect further 2A5's, 2A6's or 2A7's to be provided. Rather new models will start arriving in the inventories of European purchasers.
Ultimately, I expect roughly 200 Leopard 1A5s to arrive in Ukraine, from a coalition of purchasers. I also think you'll see 28 total Challenger 2's from Britain

arrive by 2024, and a second batch of an additional 31 M1A1's (62 total) from the United States

, with a 2024 delivery date should also happen.
As for Soviet style tanks. Poland

will probably send another 30'ish PT-91's (as their new kit arrives) and, eventually, 50-100 T-72's and T-80's will be purchased from 3rd parties and sent to Ukraine at an undisclosed time frame.
At this point, I expect that to be roughly the total tank support Ukraine can expect to get. Somewhere in the neighborhood of 400-500 more tanks than have already been announced. Most by 2024.
Even more interesting to me are the IFVs. I'll be curious to see how quickly the 200 Rosomak's purchased from Poland

will arrive in Ukraine. I'll be interested to see if USA

announces another 100'ish Bradley M2 ODS. I'll be interested to see if Germany

announced more Marder IFVs as their new ones come on line. Similarly, as Britain's

new IFV's arrive, will they be willing to part with their older Warriors. Sweden

has promised 50 CV-90's. Can they afford to send any more and can other other countries that use them contribute some as well? Will a wildcard such as Canada

step up and send some of their LAV 6.0's? Will France

send a further batch of their AMX-10RC's?
