What are the new Dropbox Business plans?

According to the FAQ and e-mail I received (emphasis Dropbox's): 

• Advanced adds sophisticated admin, audit, and security tools, with as much space as you need. This plan’s feature set is most similar to that of your existing plan

The new price for the feature set most similar to that of my existing plan costs 75% more than my existing plan (60% more than the new Standard option).  Why not keep the pricing of the Advanced plan to approximately what users are paying now and offer the Standard plan at a cheaper price?  We use less than 1TB across 35 users, but we require HIPAA compliance and long-term file recovery for discovery purposes so the Standard plan isn't an option for us.

We also subscribe to Microsoft's Office 365 (E3 licenses) for the same price as the Dropbox Advanced plan ($20/user-month) which includes the Office products, hosted Exchange e-mail, etc.  We currently don't use the included storage options because we were already using Dropbox and find it easier to use.

The O365 features above are beyond the scope of what we expect from Dropbox, but from a strictly-storage perspective our O365 licenses also include:

1. A 1TB per user OneDrive account for file storage/collaboration
2. A 1TB + 0.5GB/user SharePoint storage limit (up to 25TB max).
3. HIPAA compliance, file recovery, and a very comprehensive admin/security feature set.

In our organization's case that's 35TB of OneDrive storage and ~1TB of SharePoint storage.  

While I imagine there are some Microsoft resellers salivating at the Dropbox Business customers they'll grab, we really hope Dropbox will reconsider their pricing strategy.  I'd like to know the likelihood of that happening.  The new pricing won't take effect for 19 months for us, but we need to evaluate whether we'll be around that long if we'll have to switch (i.e. Dropbox keeps the 60% increase) anyway.
