There is an incumbent interest in the investment and scarcity of .com names held in speculation.
The are millions of business that own trademark names that are in the .com TLD.
I haven't seen much generic branding of the new gTLD strings yet.
Most likely, 5% or 10% of the
commercially available new gTLDs will be branded successfully. Remember, many new gTLDs are for only company use like; .google, .ibm, .brand, or .trademark.
As for content, people invest in websites and not the TLD. Trademark will protect the development in the new TLDs and any name hijacking or traffic hijacking by a confusing similar named incumbent domain extension may result in domain name forfeiture under the WIPO UDRP

If you are holding a .com name for resale I would seriously consider any reasonable offer now.
