Bitcoin is at version 0.10 as of April 2015. Version 1.0 isn't even being planned, let alone version 2.0.
I'm pretty sure that Danny or someone explained this in some other topic about Bitcoin 2.0 in the past.
For 1.0 to be reached there should be major improvements/changes to the software. It's just some naming gimmick just like when they use '4K UHD' on televisions when 4K and UHD isn't the same.
I think by the time we reach 1.0, the hardware that satoshi predicted about wifi and disk space will be there by then, solving the "the block size is too small" problem by the time Bitcoin gets released.
