Does that answer you question? I understand that the community is working hard on BitsharesX right now. But is the plan to make a succession of competitors? If so, the future of BitsharesX looks bleak compared to Bitcoin...
The plan is not to make competitors to Bitshares X.
The new DACs that are under development, which you will get shares of if you own PTS, serve very different purposes: Bitshares DNS, Bitshares Vote, Bitshares Music, etc. They are not competitors to BitsharesX.
These other projects are being worked on by other people than the core dev team of Bitshares X. (I think?)
To summarize:
Bitshares X is the stock market and derivative exchange DAC. It is being worked on very hard by the dev team. If you want it, you need to buy BTSX.
Other DACs are being worked on as well, which do not compete with Bitshares, but instead serve other functions. If you want in on these, you buy PTS.
