I don't have a good track record of keeping plants alive as houseplants overwinter. I do it every winter. Some survive, some die. I am usually able to grow a new generation of seed overwinter, but it's hit and miss. I'm intending to heat the greenhouse for a while this fall. That may help.
I pulled two odd plants that were growing in the S peruvianum patch. They have leaves that are serrated/wrinkled, which I typically think of as a habrochaites trait. I managed to break the roots from the vines, so I stuck them in water to see if they will grow new roots.
I'm intending to take photos of the larger fruits (by weight) in the next few weeks when I pick tomatoes.

My question here is, how do you know that a wild species will pollinate your cultivated tomatos?
In this area grows a wild tomato (solanum sisymbriifolium) called tomatillo by us. I would like to know if is there any chance for it to pollinate my tomato plants. I'm intending to start a "dry whether resistant tomato" growing project.

The black dotted lines are one way pollen flow only. The red dotted lines are possible pollen flows that depend on the particular genetics of specific offspring of the inter-species crosses. As with anything biological, these are approximations, and once in a million occurrences are possible, since plants produce pollen super prolifically. I didn't include all 13 tomato species in the diagram, just the 9 that I'm working with in my garden.

We devoted a lot of resources and labor into selecting for promiscuous flowers and out-crossing plants. This growing season, we are selecting for blight and disease tolerance back east where the ecosystem is problematic for tomatoes.
Oh, and can't forget to mention the taste. Oh my. Intending to select for fruitiness this summer, and against tomato-like taste.
