Hi jdc,
Glad to hear you're excited about Bookie!
In answer to your question - if you mean "will DApps like Bookie be available in the Peerplays wallet?", then the answer is no. Each DApp will be its own standalone application. The Peerplays wallet will remain as a wallet, where e.g. profit share, voting, and affiliate fees will be handled (and it will be getting some upgrades through 2018).
Thanks!
