Goliaths are, quite frankly, a poor attempt to give players a big race without actually giving them a big race. Mechanically, all medium races are the same size, so goliaths are a fake big race. You could play a tall human or half-orc and have all the RP benefits/penalties that goliaths have, so they aren't that much of a rp/fluff big race, either.
There are PPs for goliaths and minotaurs (Stoneblessed and Beastblooded Minotaur, respectively) that have a feature which increases their reach by 1. And there's an ED (Eternal Defender) that increases your height and weight and increases your reach by 1. But that's the closest way to emulate being Large. You're still a Medium 1x1 square creature instead of a Large 2x2 square creature though, so you'd still be a fake big character.
I don't see large ever happening, as it would be completely and totally broken. Defenders and anyone with close burst/blast powers would become off the wall. Think about a large fighter, for instance. Now you have that much extra area threatened with combat superiority alone. Not gonna happen.
There is a Druid ED (Sovereign Beast) that lets you turn Large when you wild shape. They have a fair number of close burst powers. But then again, it's an ED.
I have tabaxi and merellin (essentially dolphinweres) in my campaign.
I love tabaxi! I had one in a 2nd Ed. game. Good times!
