Its too close to a March or April release. If she is planning on doing any promotion at all there would already be a single out. Look at Britney, her new single came out 2 weeks ago for a CD coming out early March. Lady Gaga's new single is coming out next week for a CD release of May. I could be wrong though. She could update use tomorrow for all we know with a new single coming out this week or next. Its all just a waiting game.
She's finished with the album. So we know there won't be much of a wait between single to CD because it's already done. Its just a matter of her getting the promotion stuff done. All that stuff takes time. Photoshoots, getting official lyrics for booklet, making the booklet, printing of CDs. Planning a tour, if she does. Calling venues for those shows. Planning on other types of promotion: Radio, TV, etc. It all takes time to get it together.
I say just hold tight and before you know it, you will have the CD in your hands.
*for all we know she may not have a distributor yet. We don't even know if shes with the Inc or not, or any kind of label for that matter. Though I am pretty sure The Inc. is out. So shes probably doing this by herself or indie style, which makes the above even harder.
