They would be used J-10Bs, which would be a bit worse. But as of now the deal isn’t officially confirmed yet.
There was information that HMD was at some point considered for future F-2 upgrades, but not any proof to actually confirm it was tested and it isn’t on any service F-2s either.
We have the latest F-2 already, the best we could see would be better missiles such as AAM-4B or AAM-5, which also have equivalents from other nations on better airframes. I still hope we can see them eventually (alongside an early F-2 to fill the hole when it moves up), but it wouldn’t really be top tier.
