Update: As expected, we are hearing that this is a bug which is currently affecting all RA title. Apparently the UFC demo is listed for £99.99. Also, on the PSN Store the demos are all listed for free, backing up our theory that this is all due to a bug.
If anything changes and this doesn't rectify itself then we'll let you know.
On this subject, would you be happy to pay a fee for a demo?
Original: The demos for both EA Sports UFC and FIFA 14 are listed as $4.99 on the Xbox One.
We have checked ourselves and see that both are also listed in the UK store for £3.99. As you'd expect, we are presuming that this is some sort of mistake, but if not then perhaps it marks the start of a worrying new trend - charging for demos?
