Turns out the UK version of the Samsung Galaxy S4 won't be getting the new octa-core Exynos 5 CPU after all, despite what Samsung indicated at the GS4 launch event a week ago.
Instead it'll be the 1.9GHz quad-core Snapdragon 600 processor powering UK Galaxy S4s, which is no problem in itself, but having been promised the eight-core processor it's hard not to feel a little disappointed.
We have Omio to thank for revealing the about-turn, which clarifies Samsung's original press release, which revealed that the two processors would both be pushed into service in the Galaxy S4, but would be "differed by markets".
However, word from the launch event itself was that the UK would be among those markets getting Samsung's own CPU, yet Samsung's own take is now that “in the UK the Galaxy S 4 will be available as a 4G device with a 1.9GHz quad-core processor”.
That's not to say the Exynos 5 won't be appearing in some markets, of course, but at this point Samsung has decided to retract its position and is refusing to reveal any further details for the moment.
It's also not saying whether the change of plans is the result of any kind of supply issue, a strategic move for one reason or another, or simply the result of a miscommunication.
With both CPUs very much brand new there's no head-to-head performance or efficiency data for us to compare their respective merits. However, with the Exynos 5's eight core setup specifically designed to ease power use where possible, it's likely Samsung's own CPU will be the slightly more battery-friendly of the two.
We'll no doubt know more as the April 26 Galaxy S4 release date approaches.
