I got this in the mail today :

I wanted to send out an email and let you guys know that we recently patched HoN to include a brand new front end interface, match making, a tutorial, optimizations, and quite a bit of polish.

To coincide with this new patch we have also announced the beginning of our Open Beta. On Wednesday, March 31 @ 4:00 PM PST (-8 GST) we will begin accepting beta registration which require no key. When Open Beta begins the pre purchase incentives of the Golden Shield, Golden Name, and Taunting (SMACKDOWN!) will no longer be given to accounts.
