In a blog entry posted on Friday, SEGA of America announced they will be attending the annual Penny Arcade Expo this year in Downtown Seattle, WA. The event will run from September 3rd until September 5th. SEGA will be bringing along playable demos of their upcoming releases for attendees to try out, which include two Sonic titles, namely Sonic the Hedgehog 4: Episode 1 and Sonic Colours. No details are given regarding what platforms will be there and whether the demos will be of newer builds.

In addition to this, SEGA will be hosting a community event in their Gameworks arcade, located right across the street from the PAX venue at 8pm on September 4th.

We’re throwing a community event to celebrate all the fun we’ve been having in the SEGA community; if you are at PAX or around the Seattle area, we want you to attend! The event kicks off at 8pm on Saturday, September 4th right across the street at the SEGA Gameworks Arcade. It will be first-come, first-served, so get there early if you want to be guaranteed a spot inside. Attendees will have access to free food & drinks, exclusive SEGA swag, musical performances, free Arcade play, and raffle prizes throughout the night from SEGA’s past and present.

You can RSVP for the community event at the Facebook event page.
