I've found that for the most part today, people don't latch onto domain names like they did years ago. Whereas Loans might have been a worthwhile buy for $3 million in 2000, and there are some domains that still fetch six figures on the auction block, I don't foresee these new domains catching on. Who wants to type out weightloss.guru on their virtual keyboard today? Look at how many domains are purchased for their long tail value, yet the value behind EMDs' is questionable.
You might be able to utilize the new domains for their "authority" worth (in the sense of how a user "recognizes" a domain, not as in SEO value).
