As long it (UE10 or UE11) improves upon the e.530, I'd probably not regret getting them.
They are steep, but so is everything else I'd get instead. It wouldn't be for at least a month or two, I'd imagine.
Plus all I'd really be doing is delaying my other purchases, i.e. music, which I'd just get later anyway.
edit: JBL, I've not heard the triple fi, but dont plan on getting them, as I'd rather step up to customs, I think.
