Rents going nowhere in Boston?

In an article at CNN/Money entitled "Rents heading up in '06" I found these numbers for the most expensive rental cities in the US:

City - Avg rent - % increase(12 mos. ending Mar 31)
1. New York* - 2,400 - NA
2. San Francisco - 1,669 - 10.3%
3. San Jose - 1,429 - 8.6%
4. Los Angeles - 1,422 - 6.8%
5. Orange County - 1,393 - 8.1%
6. Boston - 1,350 - 1.2%

Only one other city in the top 20 had a rental increase lower than Boston's. Keep in mind inflation was running ~3-4% over the past 12 months, so rents in Boston actually decreased over the last year in real terms.

Will this performance change anytime soon? I for one doubt it. Too much new construction in the pipeline (see here) for a region with flat or declining population (see here), and don't forget about unsold houses/condos that will end up back on the rental market eventually.
