I keep seeing price estimates of $550 and if that is USD, then I think they are making a big mistake (ala Nexus 6 by Google). To me, I saw the point of this phone as something similar to the Nexus 4/5 - a phone that offered a lot at a favourable price over the competition.
From a Canadian perspective at least, a price of $550 USD will mean an end price of around $780 CDN after shipping, currency conversion (which is at about 16.5% right now) and taxes on delivery. That's nearly $300 more than it is for the OnePlus One (which runs about $500 CDN depending on the province you are in). I can't see anyone up here wanting to go that route since it is the same range as every other Android flagship (which run between $600-$700 plus tax) and unless things improve drastically on the customer support front, there is still a lot more risk and hassle buying a phone from OPO than going to your local mall and picking up a phone. If they get as good as say Google is with the Nexus phones (I had easy RMA experiences with them numerous times with the Nexus 4 and 5 where I got brand new phones in about a week) then that may change my opinion.
Of course, Canada may not be a huge market for them and it's not like our weak dollar is their problem but I think they are selling quite a few OPO's here now and that market I can easily see drying up real fast if they raise the price that much. Thought I thought the same for the Nexus 6 as well and maybe that is selling well in Canada despite it being twice the cost of the Nexus 5.
