Burlesque has been the most impressive of all the openers for quite some time now and its huge ~10,000 number last week says a lot. The film is appealing directly to the core of Twitter which is going to drive it ratio up above the 2,000 mark undoubtedly. It also doesn't help that Christina Aguilera has a couple music videos out that are always tagged with #burlesque and drive up the numbers further.
This should undoubtedly have the highest ratio on the weekend and 2,000+ is assured. The additional traffic from the music videos will also inflate its number and might bring it closer to 2,500 or 3,000. The comparative numbers are all over the place thanks to its unique circumstances but with this above average ratio in mind a five day tally of $19-$20 million appears likely.
Keep in mind this number is adjusted from the 9 mil they thought it would bring in after the first trailer was released. I still say it'll post over 21 mil for the 5 day weekend, close to 25 mil.
They also have:
Tangled: over 35 mil
Faster: 15 mil
L&O Drugs: 13 mil
