If you purchased obj 263, you will get obj 263(tier9) and 268 v4
If you have researched obj 263, the 268 v4 will be researched
If you have purchased su-122-54, it will be replaced with obj 263 (tier 9).
If you have purchased obj 430, you will get obj 430u and obj 430 (tier9)
If you have researched 430, 430u and 430(tier9) will be researched
If you have purchased t-10, you will get obj 257 added to garage (doesn't say t-10 will be replaced)
If you have researched t-10, obj 257 will be researched (not clear, but I think both t-10 and 257 will be researched)
If you have researched is-7, all exp on t-10 will remain..
If you haven't researched is-7, all exp on t-10 will be transferred to 257
And yes 9.22 will not have tier 10s for 257 t-10 line and obj 430 v II line
