I guess I was not the only person who saw this. On the official Orkut blog, the Google team published a post (which they now have deleted--it was originally posted here) highlighting a new look for Orkut email.
Here is the full post (with their screen shot) below:
(Official Orkut Blog) We are constantly working to make your orkut experience better, and while this includes adding new, useful features on the site, like new search features and support for applications, it also includes improving your experience when you are not logged-in to orkut.com. Recently we released a better orkut experience for your smartphone, and now you'll see snazzier emails from orkut.
We decided it was time to change our emails to give them a look and feel more like orkut.com pages. We started by giving a new look to the emails that are associated with orkut's most popular features: scrap alerts, testimonials, friend requests, photo tagging, crushes and teaser alerts, as well as the emails for social events, which is a brand new feature.
Now, you will be able to feel like you're inside orkut even before you click the links sent in our e-mails.

I do not know why they pulled the post down, although you can see "shadows" of the post thanks in part to a Google search (note: how ironic?)
Fortunately a copy of the post was saved in my feed reader, although I am wondering if anybody else came across this in their site feeds? (or email subscriptions?)
Update (9/27): Google finally republishes post on their blog.
