few months i think they should do almost no fees/ and fast.

The lightning network is going to be a very big thing. I think I have seen some demo of it and it seems to be working really good. As long as there is no conflict between sender and receiver the transaction is almost instant.

There is a testnet running Lightning right now, search around and you'll find about it.

At present its only in paper but surely they will implement it. But it will take some time to implement it and the launching date is not yet announced . If that comes into reality then no will be able to predict the price of bitcoin because implementation of lightening network is going to solve all its drawback. When its launched definitely third party wallets will launch an updated version which is compatible with lightening network for sure.

no it won't kill the high fees. LN is an addition that will work on top of the bitcoin blockchain and if people use it more, it can help decrease the number of on chain transaction and the backlog a little bit and decrease the fees because of that. but eventually you need to make transactions on chain to get in and out of LN and that requires fees and they may even go higher if LN helps with more bitcoin adoption and more users which means more transactions ...

LN is a protocol just like bitcoin. i think we can call it a set of consensus like rules. there are currently a lot of projects being built around these just like how there are  a lot of bitcoin wallets built around bitcoin rules.

in other words the same way there are bitcoin core, bitcoin armory, electrum, multibit, blockchain.info, greedaddress, and 100 other wallets there are also many LN wallets.
LN is already launched and working. these wallets are in beta and being tested as we speak.
then we need adoption by everyone to start using it.

You can see here how the development is doing and It's already being tested on the mainnet. In fact, TorGuard VPN is already accepting payments from LN and you can buy games and recharge your phone using Bitrefill (in testnet for now). As for the release date, I couldn't say it better then Jameson Lopp‏.

1. No one can tell that for certain. But without it Bitcoin is going to stagnate bitterly and lose all relevance fairly quickly, maybe within a year or two. Competition is too strong.
2. If everything goes smooth, it should be fully deployed in a few months. In fact you can already use it.
3. No third parties will be required. But just like with SegWit, not all wallets will support it at the first notice.

I don't think you understand LN.

Why would you open/close channels constantly? That's the whole concept. You need to open a channel and stay open so others can use your route too.

You don't need to open/close unless you want to lose money.

Methinks, this is exactly what's gonna happen if LN takes off for real. To understand this, we should first understand why the fees are so high today. They are high because there is a tough competition between senders for the inclusion of their transactions in the next block. Whether this competition is artificial or natural is another question, though. So if the number of on-chain transactions goes down thanks to Lightning, the competition should subside as well. But this will lead to faster confirmations and thus lower fees unless miners will start to ignore pending transactions and mine empty blocks, of course.

1. Its in alpha, so another 2-5 years and hell knowa what will come along it just so speculative right now
2. Years, for BTC decades
3. There is believes it brimgs centralization to BTC, google
