I remember someone found a flaw in this protocol so it never gained much popularity with Bitcoin developers, and I don't consider Litecoin devs serious according to their very low github activity.

Are you referring to misleading article which claim Grin MimbleWimble is broken[1]? While some of details is true, it's misleading article[2][3].

I don't really see it added to Bitcoin though

Not unless they want to make bitcoin the new monero. Grin

Even with MimbleWimble, Bitcoin can't beat Monero in terms of privacy. Bitcoin would need to implement additional technology such as Ring Confidential Transaction (RingCT) with Bulletproof or zkSNACKs and make it mandatory. But since it require hard fork and massively increase transaction size, i doubt anyone would support it.

I recently came across an article about Litecoin implementing MimbleWimble which I believe was planned for BTC for a couple of years now.

So I'm curious, do you guys have any information about when to expect this upgrade and whether there are some other (maybe better) privacy protocols on the work?

And for those who are unfamiliar with MimbleWimble:

Moreover, Mimblewimble combines cryptographic protocols such as Confidential Transactions (CTs), CoinJoin, Dandelion, and Cut-Through to achieve a higher level of security and anonymity. In general, these protocols help conceal transaction information.

I believe it's currently released, and it's ready for signalling for activation by the miners.

Those other coins' developers are working for Bitcoin ser. The Core Developers will decide what implementations to use for the advancement of the protocol.

I don't really have knowledge about MimbleWimble protocol but regarding it having flaws I have to say Grin[1] is an altcoin that was built using this protocol and has been running for about 2 years. I don't really see it added to Bitcoin though.

I don't think we are ever going to see MimbleWimble implementation integrated into Bitcoin, even if it has better privacy than in current Bitcoin blockchain.
I remember someone found a flaw in this protocol so it never gained much popularity with Bitcoin developers, and I don't consider Litecoin devs serious according to their very low github activity.
That being said, I would love to see something similar that would improve Bitcoin privacy and kill all privacy altcoins, but I think it's not going to happen any time soon.

If we take into consideration that Litecoin was the first blockchain to experiment with and introduce improvements such as the Lightning Network or Segwit, we could see the same thing with MimbleWimble if and when it gets added. It's all just theory and doesn't have to mean anything, but I remember reading opinions of some Bitcoiners who said that Litecoin is nothing more than just a way to test new technologies that will eventually be introduced to Bitcoin if it goes well. And history often repeats itself.

Here's short version of what i know, CMIIW.

1. There's no MimbleWimble implementation proposal on Bitcoin network[1].
2. Dandelion has some weakness and it's pull request was rejected[2] due to security concern[3]. Dandelion succeed by Dandelion++, but there aren't many serious discussion about implementing it[4].
3. PLTC (which aimed to replace HLTC by using Taproot) is still on early draft[5] and i don't expect it'll be ready in this year.
4. BIP 151[6] which aim to encrypt connection between nodes has been withdrawn and it's implementation on Bitcoin Core has been stopped[7]. It's successor (BIP 324) still in WIP[8].
