Haven't listened to the podcast yet, but in the past at least, wizard has publicly claimed (whether truthfully or not is a different matter) that the games that make it in are based on the current hype level. If a netplay function is created, and if it can revitalize the scene, that would build hype. It would at least boost our chances of getting into the official EVO roster again from the current 0% to like 2%.
I think the bigger problem is that they usually only have 5 or 6 games at evo due to time constraints. With UMVC3, SSF4AE2012, SFxT, TTT2, Skull Girls, and MK, thats 6 games already. So unless TTT2 doesn't get released before EVO 2012, then we don't have a shot in hell.
However, none of this matters because those that WANT to play melty will still just setup there own consoles/pc's.
