I find that possibility very likely, she promised she'd come back stronger, but there are always unpredictable things that may occur and interfere her will to come back. It's very important thing that her mum retired at the same age when Hikki went on hiatus. On that time she was pregneat, right? That's why I think the most possible scenario isŁ Utada wants to build a normal family, like almost every woman and there's nothing wrong about it. Still, if she wanted to do it, and had it in mind from the beginning, I wish she told us eariler via twitter or official page. If only she tweeted more, we could get to know something, not too much, but at least we'd be sure she's doing fine. And that's very precious information for us, isn't it? If she never comes back, it'll be sad, but I can understand it. Don't forget that during her career she made 8 albums (7 if you really don't want to count Precious), it's more than some bands have after longer career, look at 30 Seconds to Mars, band made in late 1990's and they have only 3 albums, same with Evanescence. She's achieved so much and I admire her for that. I hope she will come back, anyway.
