This thread is full of shit.
The developers are working on a solution, that seems to be a better solution than BIP101. I believe that even XT just went with Gavin's 2MB BIP proposal (for now).
A paper is being written, which details the implementation. Let me just tell you this, if you are doing something as big as this, where you change on of the core parts of a system, you could seriously screw it up. We may not know now, but it the future could be an evident issue. That's why everything is being done somewhat slowly.
For some reason, people here seem to be attacking some proposals because they don't agree. For example, SegWit. SegWit's primary purpose is to fix malleability issues caused by txs signatures; whilst it does decrease the size of individual txs.
I don't wish to seem like I'm attacking ProHashing, but I believe that he is not really a developer. Whilst his efforts are appreciated, in end, it is the mining pools who decide on what to do.
The core devs mostly pay for themselves out of their own pockets, and funding is important if we wish to have an active dev team.
