The Source has posted the variant cover to Flash #6.  Featuring artwork by Mike Choi, the cover shows the Flash frozen mid-movement.  It has been revealed that Captain Cold will make his first full appearance in Flash in issue #6.

Choi is also quoted in the post, where he talks about some of his artistic influences:

From the get-go, [Flash editor Brian Cunningham] told me to try and infuse more dynamism to my figure work by looking at artists like John Buscema and Wally Wood, and hopefully that’s coming through bit by bit as my career progresses.

Interestingly, the solicit up at DCComics.com has not been updated to reflect the new content in issue six and still reads as below.  It has been stated by writer Brian Buccellato that the CSI story is “off the table.”
