Gopi, in that case BlueWidgets.tld will still serve rather nicely as a memorable and easily marketable website address, especially for a website about "blue widgets".
No matter the future type-in, logical, addresses - where the web address is the website subject matter - work.
That's the charm of the generic subject matter, natural addresses . . I mean domains . . I mean domain as marketing advantage . . I mean webaddress marketing. ;0)
YMMV, but I believe the noise about "brand over natural address" is slowly diminishing. PPC is helping quiet the noise. Simple logic, too, is taking hold.
