*SPOILERS!*



Since Aeris left together with Zack, I like to think they got together in the Lifestream. As for Cloud and Tifa, have you guys seen the Last Samurai? There the look between Nathan (Cruise) and the woman in the end told us so much, we didn't need confessions of love or kissing to know what they were thinking, and the ending scene felt so much deeper and more emotional without any kissing. The same for Cloud and Tifa, IMHO. Just see the loving look in Tifa's eyes when she's looking at Cloud. There Cloud is also looking at Tifa at that point and smiling. The ending music is even titled "Cloud Smiles" in the soundtrack. Also, when Cloud is told "Welcome home", he's looking at his friends, and I think the screen (showing what Cloud sees) is centering at Tifa. When Cloud says "I'm back", and just look at his eyes there. BTW Didn't you hear similar words in (FFX-2 spoiler)FFX-2's happy ending between Tidus and Yuna? I don't think Square Enix ever makes a decisive announcement about who ends up together with whom since there's so many fans for Cloud/Aeris and Cloud/Tifa alike.
