Huawei's not exactly a household name with the tech blogs, and they have not released any news about their WP8 phone. Besides, for the western side of the globe, you get the Nokias, Samsungs and HTCs first anyway.
I'll probably wait for their devices to be released and reviewed before buying anything. They seem to be a bit like LG when it comes to Android, as they make decent hardware but lack the custom UIs that look as appealing (and, by now, familiar to consumers) as those from Samsung, HTC and Sony. So, if they play it right WP could probably suit them well.
