Their eyes are on D.C.: Capital area said to have good shot at Amazon HQ2

Has there been any indication of the new HQ's purpose? Duplicate functionality, admin, technical, etc.?

I've wondered why they wouldn't simply locate the new HQ at or near their existing NoVa location(s).

If I'm (not) betting, I'd flip the Dublin bookmaker's DC-area rankings: NoVa would seemingly have the things that people "want" (traffic and all), while Maryland wouldn't seem to resonate, and DC seems better suited for a small footprint/satellite office (lawyers and lobbyists).

Please don't come to DC. Traffic and transit and everything is bad enough as it is.
