I don't think Cryptonote classifies (Bytecoin specifically - from which Monero has been forked) as 2.0 - beside, first the Cryptonote developers need to solve blokchain bloat issue.
2.0 would be Zerocash, NEM and few other maybe.
Zerocash has a trusted accumulator, so I won't be using it.
There are issues with it - yes - but I was merely stating fact that it's interesting project/research which classifies as 2.0.
Also what is the CryptoNote blockchain bloat issue?
I don't want go into discussion about particular alt, but since you've asked:
Blocks are much larger than Bitcoin's for example - so the blockchain gets very big rather fast.
Main problem with this is, when (and if) solved, only a fork into new coin can deal with already generated blocks.
And yes, we all know Monero was forked, that was because we didn't want to mine a chain that had a hidden two year pre-mine.
Again, I don't want go into discussion about particular alt - so only very briefly my opinion on the fork:
That leaves the problem of the development.
Many can fork, but I'm sure not many fully understand what they fork, so this is an issue. Until you can secure original developer's cooperation, or fork's developer proves he does - through development.
Otherwise you risk slowly falling into a dead branch.
See the Litecoin situation, a fork is always required when original developers get greedy.
Do you mean that Litecoin fork is needed?
Doesn't look to me like market needs second Litecoin.
