Thanks all for your imputs
@Mouthymerc: Ya I can understand why there isn't a pdf for the Beta Adventure so thanks for confirming it.
@Ironman: I totally understand where your coming from with the wait for full release I was like that too but the more I read the Beginners Rulebook and Adventure Book the more I kinda wanted to see what had changed since the games announcement at the 2012 GenCon.
@Scott McFarland: Thanks for sharing the site I know have another site to buy from.
@Lupex: Thank you for the offer of letting me but your spare copy of the Beta Rulebook and sharing another site to buy from (Though when I looked I didn't find the Beta Rulebook in any search involving star wars as the keyword or having FFG as the author)
@Kallabecca: You are right Spring 2013 can mean anywhere between late March early April to late June early July.
I'd also like to note like I mention in my reply to Ironman that I've read the Beginner Books many times over and as well as learning of the changes since August I would love to learn more about the adversaries groups can face and the classes and races that are available at the moment.
Thabks again guys for your advice.
