Will Harriet Tudman "replace" Andrew Jackson on the $20 bill; on all 20's; only on the front with Jackson on the back and only on certain series of the bill?

Here is how the USA Today words its news release.  Be careful to read between the lines and note what is not said,  and,  before you start ragging on Jackson for being a "slave trader,"  keep in mind that he was a Democrat  ~  editor. 

Update:  This conservative blog sees no problem with the decision to put Harriet Tudman on the 20 dollar bill.  Political correctness?  Of course  . . . . . . .   so what is wrong with being correct,  once in a while?

USA TODAY:    Abolitionist Harriet Tubman's image will appear on a new series of $20 bills, becoming the first African-American to appear on U.S. paper currency and the first woman in more than a century, the Treasury Department announced Wednesday.
In replacing replace President Andrew Jackson on the front of the $20 bill, the Treasury Department abandoned a previous plan to have a woman replace founding father Alexander Hamilton on the $10  . . . . . . .  
The $5, $10 and $20 bills will all be redesigned over the next four years, but will be put into production at various times over the next decade.
The long-awaited currency redesign will have a cascading effect on bills of all denominations over the next decades, as new security features are introduced to make the bills harder to counterfeit. New bills will also have tactile features to make them easier for blind citizens to distinguish.
And, Lew said, the redesign will affect the fronts and backs of each denomination. "We want people to pay attention to the whole bill," he said. Among the changes announced:
► President Lincoln will remain on the front of the $5 bill, but the image of the Lincoln Memorial on the back will be redesigned to depict historic events that happened there: Opera singer Marian Anderson's 1939 concert and Martin Luther King Jr.'s 1963 "I Have a Dream" speech.
► The back of the $10 bill will tell the story of the women's suffrage movement, which culminated in the 19th amendment giving women the right to vote in 1920. Among the women to be honored on the back of that bill: Lucretia Mott, Sojourner Truth, Susan B. Anthony, Elizabeth Cady Stanton and Alice Paul.
► To make room for Tubman on the front of the $20 bill, Jackson will be moved to the back where he'll be incorporated into the existing image of the White House. Lew said that image could depict the statue of Jackson riding horseback in Lafayette Square across Pennsylvania Avenue from the White House.
Jackson, a democratic populist who opposed the national banking system, has seen his stock fall in recent years because he owned slaves and persecuted native Americans.
