Like I say
".cam is just a ranking edge you can buy for around $30year -- that is chickenfeed for a shot at better SERPs. A few sales pay for the whole years registration price

"
Doesn't work out? 301 the name if it makes sense or just drop the name, keep the HTML -- and try with a new name.
If you are developing a branded cam site, or for that matter whatever extension, add to the memorability of the name moniker ... Top-of-mind branding is a long term expensive project. I 'own(really legally a leasehold)' both the .cam and the .cam on some SLD names -- I will redirect the .com to=>the .cam for the branding value -- that is the ideal situation for now. With 500+ new gTLDs it is not economically feasible to URS Arbitrate every registration if you have a trademark ($500 to $1,000 ea).
On the .com side -- many names will end up dropped if they are not in use or are not particularly valuable.
So, having matched domain names in a few key TLDs will become the rule. It's probably cheaper than obtaining a trademark registration in most cases where you can't get the registration. However, spending 10s of thousands on a name with no trademark is lunacy.
