Will the Arduino uno r3 be discontinued?
I hope not.
Will the Arduino store start selling the R4 in the starter kit?
Even if it does then you will stil be able to buy clones of the UNO.

The Arduino UNO R3 will still be available and supported , at the side of all makers who want to work with its 8-bit AVR microcontroller.

I don't think so.
R4 is not a new version of the R3, it is a completely different controller. I think that it was a error to name it as "next release of R3", this bring a confusion to users.
However probably it was just what arduino team wanted?

Agree with that.

Like the UNO WiFi Rev2, that causes endless confusion since it uses a completely different processor from the UNO and the UNO WiFi (which also uses a completely different WiFi chip).

Also was the redefining of the Nano into a form factor, rather than a specific board confuses many people even years after it happened.
Poster - I have this code running on a Nano ....
Forum member trying to help - What sort of Nano do you have?
Poster - I didn't know there were different sorts.

absolutely.
"nobody" associates UNO with a form factor.
Nothing learned from "NANO" Every and others.
There would have been enough remaining numbers in Italian or unit prefixes to chose from.

I think they called it the UNO R4 for a reason
The R4 costs $20 (USD)
The official R3 costs $27.60 (USD)
Why would I buy an old R3, when I can buy a new R4 for less money.
It will be retired by lack of demand

I hope not. I wish to buy an R4. But I don't want R3-based projects to be obsolete.

I do not think Arduino UNO R3 will be discontinued so soon but like already in the first answer from @Grumpy_Mike, there will still be plenty clones available. Nano is a option too.

What the Arduino Uno R3 has going for it, is the huge base of software, libraries and online support.

Absolutely!
I suspect it's so different, that they were scared it wouldn't take off - so they're using the UNO name to give it a kick-start.
Like car manufacturers will sometimes give a new model a completely new name, but sometimes call it a variation on an existing (popular) model.

They'll only be obsolete if they rely on specific feature of the R3.
One of the great things with the Arduino framework is that it is portable ...

Not sure about that.
Remember cheap clones.

A more powerful processor doesn't necessarily mean more popular.
The Arduino Due was released in 2012 and performance-wise blew the socks off the Mega. Powerful ARM Cortex M3, 84MHz clock, 512KB flash, 96KB RAM, masses of on-chip peripherals and timers, all at a similar price.
By rights, the Due should have become Arduino's flagship product, but it never happened, as it just couldn't garner enough support.
Both are excellent boards though.

A post was split to a new topic: I don't see that Arduino UNO R3 in Boards Manager
More too:
Nano every.
Indeed.
And a more powerful processor is not necessarily better - if a simpler processor can do the job, why complicate it?
