Nvidia doesn't need to create a new GA103 die for new GPUs, unless they want to create lower end/ lower power versions.
The advantage to this approach is that Nvidia can use GA102 dies that aren't quite high quality enough for the RTX 3080, in a RTX 3070 Super. We know Samsung is struggling with RTX 3080/3090 die yields...
I think it could be called the RTX 3070 TI if released in Q1 2021. But more likely to be called RTX 3070 Super and to release in Q2/Q3 2021, alongside a RTX 3080 Super, which would replace the standard versions. I also think the Super GPUs will be 8nm based, as Nvidia has renewed their 8nm deal with Samsung, for 2021.
Nvidia used the TU104 die for the RTX 2070 Super, rather than the TU106 die used in the RTX 2070, they could do the same thing with the RTX 3070 Super and upgrade it to the higher end GA102 die (instead of the GA104 die used in the RTX 3070).
The rumours about a possible GA103 die I think so far have all been incorrect. If you look at the RTX 2000 series / Turing, Nvidia used the TU104 die for most of the mid-high end desktop series, rather than create a new die. Link here:

The exceptions were the RTX 2080 TI / Titan RTX, which used a higher end TU102 die, and were priced much higher.
Interesting facts about the RTX 3070 die:
60.2% smaller than the RTX 3080 die.
90.3% smaller than the RTX 2080 TI die.
Not surprising that the RTX 3070 is one of the most power efficient GPUs right now.
