GMAT Induced Dilemma

This is my first post. I'm currently sitting on two waitlists and am hoping the forum can provide some direction. Bit of a unique situation, so here goes:

I started the MBA App process late. I didn't begin studying for the GMAT until September of last year (2012). I took GMAT #1 in mid-November and scored a 690 (Q47, V38). I was not happy with the score, but I needed to shift focus to applications. Especially to make sure I could make the Haas Round 2 deadline, which was in late November. I spent the rest of November, December, and early January submitting Round 2 applications to Haas, MIT, Booth, Anderson, in that order.

In late January, I decided I needed to take the GMAT again. My rationale was two-fold. First, I was not personally satisfied with the 690, and wanted to retake in order to either improve my score or validate that 690 accurately reflected my abilities. Second, I knew that 690 was low-end for the schools I was applying. I figured if I did better and I was on a schools waitlist, I would be able to update my already submitted applications.

I got dinged by Booth with no interview in mid February. I was invited to interview at Sloan and Anderson in early March, and waitlisted at Haas around the same time. This was all happening with GMAT score #1 (690).

On March 1st I retook the GMAT and received score #2 of 770 (Q49, V46). This wildly exceeded my expectations (I had never gotten above a 750 on a practice test, and was expecting ~720. If desired, I can speak to the score jump). At this point, I was already on the Haas waitlist, and I submitted the 770 as an update to my application. I attempted to update my application at Anderson, but they would not accept updates. I interviewed at Sloan on March 15th, and updated them with the new score in person. My Sloan interviewer was impressed, but it was unclear if they formally accepted the score or not, considering the test was taken after the application submission date. Fast forward to early April. I was admitted to Anderson, waitlisted at Sloan, and remain on the Haas waitlist.

Herein lies my dilemma. With the significant jump between GMAT 1 and 2, my expectations for school have changed. With score #1 690, Anderson was a target, and Booth/Haas/Sloan were stretch. With score #2 770, all schools are within range, and scholarship expectations are up.

Considerations:
1) Actively pursue Haas/Sloan waitlist, hope to get in with no scholarship, keep Anderson as safety.
2) Dump Anderson with no scholarship as it has fallen out of target range with new score
3) Reapply to Haas, Sloan, Harvard and Stanford for class of 2014, hope for some to a lot of scholarship money
4) Other?

Right now, I'm leaning toward pursuing Sloan and Haas waitlist aggressively, and possibly attending Anderson if Sloan/Haas don't pan out. Friends have told me that with a 770, many doors in the top 5 will open, and that I should chalk this years cycle up to a mis-fire and re-calibrate my expectations next year. Also, I understand the school decision depends on goals, however I'd like to keep this discussion focused on the impacts of the GMAT retake.

Anybody else experience this or have thoughts?
