They've already eclipsed just about every other act to come out of the show, except Leona Lewis. Will they see more worldwide success than the very UK-only-based Lewis?

One Direction has a Brit. She has nothing.

Olly Murs >>

Yeah, by far.

Leona... I mean her #1 hit will continue to have sold more than their whole discography...

I think Rebecca might end up being bigger than them.

I LOVE ONE DIRECTION!!! and yes, probably, unless they produce a Rihanna duplicate.

Alexandra Burke is by NO means the least successful She just doesnt have the advantage of having lots of horny girls fingering themselves for her. But yeah I see 1D being the biggest thing out of XF.

But a Brit doesn't translate to global success.

Leona do not have a Brit?




And to answer the question,Yes.

Will they have as huge as a impact as Leona? No. Her album did 200k first week. But it's too soon to tell.

This.

Ugh they better not.

I hate them.

I'm sure people thought Leona was the next big thing when Bleeding Love was a massive hit (the #1 hit of 2008!), & then she undeservedly faded in the US. She really deserves a lot more than she got.

One Direction will be huge, they already have a following. I'm hoping thinking Cher Lloyd will have a huge breakthrough too.

it's too soon to tell.. They are a boyband though and we all know boybands don't last.
