I have to say definitely not. Edwardsiana has people's imaginations at the moment because it's not commercially available, but it's not the be all and end all. I can remember when species that are considered common now were the 'must haves' of the moment. There are plenty of new species around, I have a couple of friends who've come back from Sumatra, Sulawesi and Borneo in the last few years with seed of what they believe to be new species, and we're just waiting to see how the seedlings turn out. There are also plenty of areas in Indonesia and PNG that are perfect Nepenthes habitats that are completely unexplored, so new species are still out there in the views of many.
There's some really exciting stuff around at the moment, but you'll not hear about it until it's formally described. As you know, whoever describes first gets the kudos, so those who've found new species keep it secret until it's been published, telling only a few trusted people. It can take years to get things published, so it's a timing issue.
So, as I always say, be patient, and you'll see some cool stuff.
