Time Played/Achievements Wiped?

I thought I read somewhere that achievements and stats would be wiped from people who had previously played during the beta, however, mine is all in tact on my Steam page. I can't check anything in-game or in anymore depth, as a lot of stuff is blocked at my work, so I'll have to check when I get home.

Just curious does anyone else still have all of their stuff?

Also, off-topic, do the people who pre-ordered through Steam get the pre-order helmet yet?
