Will I get the same carrier deal on an S26U when it comes out as the S25U currently?

I'm at $50/month for the unlimited Google Fi plan and have no problems with it, but have a Pixel 8A and would loveeeee to swap to the Galaxy lineup.

T-Mobile is saying 60/month for essentials and I'll get an S25 Ultra for 12.50 a month @ two years. I'd happily pay a total of 22.5/month for this phone. Should I pull the trigger now or will this same thing probably be available for the S26U in a month or two with pre-orders or when it goes live?
