You are correct a rebadge won’t be as cheap but it will still be significantly less expensive than the 150-450 and longer.
At B&H the 150-450 is on sale for $2000 from a list of $2500.
The first generation of the Tamron is listed at $1070 and on sale for $900 to $950. So a rebadged lens might be $1200-1400.
But as I said, it is my hope and certainly not a guess let alone a prediction.
If it turns out to be reality then I might start saving up money.
