It depends on how google is set to focus on Moto X too. With the rumours of that being near stock as possible also - it might be a case that there is no longer the need for 'nexus' as a brand.
With Google Editions of flagships and Motorola offering near stock like experience with some (limited) customisability going forward do we really need a nexus device.
Arguably the nexus 4 with its paltry 8GB storage and lack of LTE was a bit of a backwards step going from the 16GB Galaxy Nexus, do folks want another cheaper albeit limited device, if motorola can fill the niche with the Moto X offering a cheaper version for same price range as existing nexus models - then Google doesn't really need to go down the nexus line anymore.
It's interesting and perhaps telling to see that Google opted to brand the HTC One & S4 as 'Google Editions' rather than Nexus devices too.
We will see.... but I would not be surprised if we wont have another nexus, especially as there has been a genuine lack of rumor concerning a replacement.
The Nexus 4 did have 16GB, but didnt have sdcard slot -.-
But after Google announced GED devices they were bombarded with hopeful fans asking if Nexus would continue (Nexus is a brand people know and love, and sorta hipster
) And Google said that they have no plans on discontinuing the Nexus Brand, but they also said something along those lines like, these phones are the phones we will support, beyond all else, paraphrased of course, regarding some Moto devices, and then HTC Nexus One came out!!!
Also Google said that Motorola (as they are Google, now) will not get special treatment and that they will be a completely separate group, part of Google, but, not?
Plus the Moto X, yes it has new tech like the clear pixel, etc, it is only a mid-range phone, that has been basically confirmed. However, I am hopeful that Motorola will bring out a top-range X.
Nexus will live on, and it would not be the next "Nexus 4", but Nexus 5, or something, maybe Nexus One again, with that "One" craze going around (Xbox One, HTC ONE). But I also believe Nexus 5 will be a Motorola phone, either them or HTC.
And this is bound to be a discontinue, seeings as it is only 3 months until Nexus 5, but I just thought they would make it later, maybe to clear out stock of stores, by the announcement of Nexus 5, or to be the good guy, as many people, who are not in touch with the release cycle, may buy an N4 soon before N5 launch. Maybe the UK seller didn't want to stock them anymore, not enough sales, and I would think N4W wouldn't get many sales either, so many it is that.
