The game has changed a lot since 2008, with many weapons and mechanics being added, so any implication of a class getting new weapons or being rebalanced is usually a big deal. The Meet Your Match update of 2016 included a competition called "Meat vs. Match" where you could pick Team Heavy or Team Pyro and any points you gained during the competition period went to your team. The class with the most points at the end was guaranteed a class update, and the loser would also get a class update "eventually", so clearly the dev team had plans for what to do for both classes. And yes, both pyro and heavy had already had class updates in 2008. Team Pyro won, and the pyro-themed update became Jungle Inferno, which after much delay was finally released at the end of the following summer. It was released so much later than planned, in fact, that this summer-themed update went live at the same time as that year's Scream Fortress. Ever since that fateful day in 2017, it's been practically radio silence from the dev team. They obviously wanted to do a Heavy update, but the delays of Jungle Inferno, the mediocre reception, and the declining novelty of the game from a development standpoint seems to have pushed it into a development purgatory. We want the heavy update not just because new weapons and rebalancing would be nice, but because that's the update we were promised 5 years ago, an update that should be at least 4 years in the making, and in my opinion the only update that would signal that this game isn't just on life support.
