I'm as optimistic as anyone about DC but I think reaching 700,000 residents in 10 years will be difficult. This will be 16% growth from the current population of 604,000 residents in one decade.
This is from the Washington City Paper:
"That transient constituency isn’t going away, and unlike other cities where buildings aren’t capped by height limits, it won’t be diluted by other kinds of residents, either.
The last big piece of downtown is getting built right now: CityCenterDC, which will have 674 condos and apartments total. Only 150 units are in the pipeline after that, compared to 5,444 in NoMa and 4,624 in Capitol Riverfront, by the baseball stadium..."

Downtown 800 units
NoMA 5,444 units
Capital Riverfront 4,624 units
14th Street 1,150 units
H Street, NE 1,373 units
Wisconsin Ave 500 units
Brookland/Catholic U. 765 units
This gets you 14,680 new units by the middle part of this decade. According to the US Census data, there are 2.39 people per occupied housing unit in the District, so this would put you at about 30,000 new residents by 2015. Admittedly, there is more planned for Georgetown, SW waterfront, Foggy Bottom, etc... The big question, to, is how much development there will be east of the Anacostia.
Although I'd like to see the District reach 700,000 residents by 2020, I think this is too optimistic. Perhaps 650,000 people.
