If it's not done in exchange for money or similar benefits from Sony (for instance), it's not considered product placement according the BBC's own guidelines.
Their general editorial principles state that
We must not endorse or appear to endorse any other organisation, its products, activities, services, views or opinions.
We must not give undue prominence to commercial products or services.
There must be no product placement in programmes.
Product placement is defined as
the inclusion of, or a reference to, a product or service in return for payment or any consideration in kind.
They have more specific and lengthy guidelines for "undue prominence". But they start with the obvious observation that
We need to be able to reflect the real world and this will involve referring to commercial products, organisations and services in our output.
Also further down
We must ensure there is no element of plugging when we review products or services. We should review a range from different suppliers. [...]
if we are reviewing products of any significant value, such as a washing machine or a car, we must return the product to the manufacturer or supplier.
As far as having separate news articles for commercial products it doesn't seem unusual for the BBC 'Newsbeat' to do with the major brands; e.g. a quick search found a recent for Xbox One and an older one for Nintendo.
Ofcom says that complaints about BBC's content should be directed to the latter first. And the BBC page they point to does list some complaints although it seems they are mostly about their coverage of politics.
