I know we should be hopeful and optimistic about the outcome, but... they have already taken decision which they have mentioned in the email: "We strongly believe that this will be beneficial to all our teachers and students. However, we understand that removing or updating features may have an impact."
You should notice that emboldened word, "strongly", that means the "however", they wrote after that was just to make you feel good. So, guys, don't breed false hope! Sorry, but that's what I got from the tone of the email.
I'd be great if they'd explain how they're planning to enhance the site. The last time they did a major overhaul, they promised new and cool features. I'm still waiting for those. The only new thing was the Benny Lewis language hacking thing which left me unimpressed .
