I'll be quite surprised if the stout is ready in two weeks. Three weeks @ 70 degrees is the baseline for typical beers. Higher gravities and cooler temps can take longer.
I just opened the first of my Belgian golden strongs tonight. They've been in bottles for 4 weeks now @ 70-72 degrees. Got a nice "pffft", but only a very thin layer of head that faded almost immediately. Very little residual carbonation. Of course, it's an 8.5% ABV beer, so I'm not too surprised. I'll leave it alone for another 2-4 weeks before I try another.
On the plus side, bulk aging was obviously good to me (nine weeks primary, two weeks secondary); the beer iddn't have any green flavors at all. Wonderful pear esters, great dry finsih. A little sweeter up front than I expected, but since it's still pretty flat, I'm betting that can be attributed to priming sugar.
OP - that stout style is one that really benefits from some nice aging. Try to set at least a few back for several months, and see if they aren't the best in the batch.
