Almost certainly there will be. Altho string implants are unlikely, there is for sure gonna be future developments allowing for large breasts like Minka’s. There currently are women who are as large or larger from all kinds of corners of the world, there are a whole lot more women planning to go as large (probabaly some Asian women aswell), there are implants that are 30% lighter on the market right now, implants that only weigh 30% are being developed, we have the Aeroform expanders in trial that offer light as air implant filler, developments in targeted tissue growing will eventually allow for much larger breasts. So yeah, basically a matter of time... There are things in the pipeline that will allow fatasies to come true much easier for the women who have them. For men there will come a point where you don’t need a willing partner (or even for a model to exist) because convincing androids can look however you want them to look and developments in AR/VR can make your dreams come true. Last but not least it’s my strong believe that for every model we know of there are many times more women who are not modeling at the same size, just enjoying a private existence with huge boobs.
How that for a complete answer? “Will there be another Minka for me?” If you are young enough, don’t worry about it. It’ll come.
