As much as I would like Melee and Smash to be given another chance, I just don't see it happening.In case people want an accurate timeframe to when to expect the lineup reveal, WakeupSRK typically airs a bit after 9:30 PM EST, so the reveal will likely happen between 9:30-10:30pm EST tonight.
Even if there was massive interest, they'd still need GC/Wiis and different recording setups like the other poster said. That's too much hassle and money for one game, a game that was always a side event at Evo anyway even when it was there. People shouldn't get their hopes up.
