Ok, on the SA forums these guys who are known to be Valve playtesters are leaking out small tidbits about the heavy update. One of these guys predicted details about the pyro update before any info was released, so they may be legit. Even so, take this with a grain of salt. (Also, one of the posters there is an employee of Valve)

To get to the thread, go to the SA forums and look for the thread "Team fortress 2-From Russia, With Guns"

(Read through the thread to the end pages for more talk on it)

Tidbits/Rumors
-New gametype being worked on for Heavy update. Will change TF2 forever. Reason why update is delayed. May end up releasing in September.
-Heavy unlocks solid. Clue words given are "popeye" and "ghostbusters". BEGIN SPECULATION.
-Patch has alot of stuff in it. People requesting to split it up so we get something soon.
-No Meet the Vid or word on the next one. Smaller piece of media that was announced earlier is a mystery so far.
-Apparently one of the testers for the game blabbed about the features and now its spreading around. MUST GET INFO NOW!
-Rumor that update will cost money (This is probably the most erroneous piece of info on the list)
-Rumor is that popeye/ghostbusters is some kind of weapon affecting the actual heavy model. Again, just a rumor.

Again, this is all rumor. I'll update if my internet sleuthing comes across this supposed leak. Anyone else know anything about this feel free to post.

Edit: Decided to bold all the times I mention that this is a rumor, for those who feel it is your goal to prove someone wrong on Steam Powered Forums.

"Update: New Details.

According to the SA thread, the Heavy unlocks are done. Now some are saying that this stuff should be disregarded as a member got banned for false info. The member that was fakeposting only provided info on the "popeye" clue word and that TF2 updates would cost money. So some of this still applies.

Apparently, the new gamemode is holding things up but Valve could release the unlocks now. Also, according to some playtesters, the weapons are "1 upgrade, and 2 sidegrades (one a gimmick)". Rumor has it one of the weapons will make Scouts worthless.

Anyone got the inside scoop on these rumored weapons yet?"

Incoming Heavy!
August 11, 2008 - Robin Walker

We've been a little quiet for the last week as we've put the finishing touches on the Heavy update. We thought the Pyro pack was the biggest we'd be doing for a while, due to the large changes to the Pyro, but the Heavy update has turned out to be even bigger. In addition to the three unlockable weapons and thirty-five achievements for the Heavy, we've got a new game mode with five new maps for it, a new Payload map focusing on more open spaces than Goldrush, and another popular community-made map. Throughout the rest of the week we'll be giving you the details on all this, and if all goes well, you'll have your hands on it shortly afterwards.

The community-made map included in the Heavy update is cp_steel, by Jamie 'Fishbus' Manson. After the Pyro update we received a lot of email telling us how wrong we were in our choices, and cp_steel was an easy next choice due to the way it dominated the suggestions. If you're firing up your email right now to tell us that we never get anything right, please include suggestions of what map(s) we should be looking at next.

We'll be updating A Heavy Update site with more info daily. Stay tuned!

The rollout culminates next Tuesday, August 19 when the update will be made available to all owners of Team Fortress 2.

To give all gamers a chance to check out the new gameplay introduced in "The Heavy" update, Valve will be running a Team Fortress 2 Free Weekend via Steam, a leading online platform for the delivery and management of PC games. The Free Weekend is open to gamers the world over and scheduled to begin Friday, August 22 at 11 am PDT.
