So yeah i've read some things about confidentional transactions to enhance privacy in Bitcoin, but i don't really know what it means.
Will Bitcoin enable anonymous transactions&addresses? So you could have an address and nobody knows how much Bitcoins you have/nobody can see your transactions/worth of transactions...?
What level of privacy/anonymity will these implementations provide?
When the dev's are asked this question the response is 'we don't care'
Most ppl just want to pump&dump btc to the moon, and don't consider privacy as means to the end of 'getting rich quick & easy'
As to the nature of your question, there is MONERO ( which claims to be secure ), and there is the z-cash coin family which have z-obfuscated addressses to backup the public address scheme, the thing with MONERO is its choice of ECDSA is known to be weak and have a back-door, while MONERO may be 'secure', its not secure from the ppl you should fear ( NSA wrote the ecdsa curves for monero ), like NSA wrote Secp256k1 for btc, like NSA wrote sha-256 for btc, ... THE ONLY real privacy is a coin that has no link to NSA, I think zen-cash fits that case

Again, over the years when dev's have been asked its always "We don't care about privacy"
That's ok, it opens the market up for other coins that DO CARE ABOUT PRIVACY
You have several inaccurate statements.
First, I have never once seen a Dev say "We don't care about privacy." However if your assertion was taken figuratively, privacy may indeed rank low on the list of Core changes because it would be a change from Satoshi's pseudo-anonymous design.
Second, no, the NSA is not "the people you should fear." There are similar agencies all over the world. There are commercial companies and operations that in my opinion, offer a greater threat. Facebook for example.
Third, there is no evidence for the assertion that "the only real privacy is a coin that has no link to NSA." How about the crypto-currency the Venezuelan government is deploying? How about a crypto by Goldman-Sachs?
These statements are wrong for important historical reasons, in which the NSA has actively worked with and assisted in better crypto. Other countries such as Russia kept their crypto secret, which meant it was not criticized, which meant it was quite easily broken. Therefore, having the NSA openly assist with crypto seems a good thing, not a bad thing.
I hope that makes sense...
