Regarding the first week sales of 'Roar' in the UK, these statistics may give us an idea. I believe that 'Roar' is the 3rd highest position a pre-order has managed in the UK since they started showing up on the singles chart behind 'Blurred Lines' and 'Wake Me Up'.
Avicii's 'Wake Me Up' got to #8 on iTunes on pre-orders, and ended up selling 266,000 in the first week.
Robin Thicke's 'Blurred Lines' got to #11 on iTunes on pre-orders, and ended up selling 190,000 in the first week.
'Roar' is at #15 so based on the sales above she should manage between 140,000 and 150,000 sales first week in my opinon.
In terms of 'Roar' reaching platinum, it could be a good idea to compare 'Roar' with Naughty Boy's 'La La La'. 'La La La' sold 145,000 in the first week (which is what I am expecting 'Roar' to achieve) and went platinum (sold over 600,000) after 6 weeks on the chart. So 'Roar' will probably go platinum in a similar amount of time.
Of course, these are all just predictions based on what has happened in that past, but it gives us an idea of what may happen!
