Anything is possible until proven otherwise.
While there will always be those who prefer pure animals over hybrids, crosses etc the Australian market is always going to be influenced by overseas markets purely because prices have dropped so much in the Australian market and people are finding new ways to turn a profit.
Add in animals such as reptiles have moved up in popularity in Australia and a lot of people want something different or something they have seen overseas markets, there are more and more different pairings happening all the time.
I know some people will disagree with what I have just said and that is fine I welcome it, but if you study the trends for the last 20 years if not more you can see the new fad is 'designer' herps.
