Speaking strictly about the website redesign, I think that (although nice) it fails to communicate the framework biggest selling points. Some comments on that:

* The code-save-refresh workflow: this is mentioned briefly as "hit refresh workflow" which is confusing to say the least.

* Some other weird or 'meh' bullet points like type-safety (you're using either scala or java so you take that for granted) or stateless-web-tier.

* The introduction video is long. It's fine as a tutorial, but being the first thing you can click on I expect you to sell me the framework in 2-3 minutes or so (it can be done, play is fantastic).

Disclaimer: I love play and used it a lot last year. In fact I was part of the team that put the first play application into production on LinkedIn (featured in the bottom of the play site).
