Captain America's Super Serum?

It’s been a slow news weekend as far as Marvel movie news. Now that the Hulk hype has died down, the next two Marvel Studios movies are Punisher: War Zone (Dec. 5, 2008)and X-Men Origins: Wolverine (May 1, 2009). As far as I know, the characters in these movies are completely separate franchises and won’t have any connection to the Avenger Initiative or the Avengers movie.

Though I don’t expect any Iron Man cameos, but there may be some little Easter eggs lying around in the background of these movies; kind of like Captain America’s Shield in Iron Man. This claim is totally based on what I saw in the trailer for Punisher: War Zone so it’s just speculation. If it’s not true, please don’t hurt me.

Above is a screen shot from the Incredible Hulk featuring the blue super-soldier serum(the stuff that made Captain America). Below that are some similar blue canisters in a case from the Punisher: War Zone trailer. Are they the same? Is it just a coincidence? Is Marvel just reusing its props?
