i'm fairly certain that none of those will get any real consensus besides core,
core is aiming as well to increase the limit to 2mb, so the other are obsolete
they seems like a way, for some dev to say " this version is mine, i made it..."
Do you have any updates showing that core devs are moving toward a 2MB max block size? I agree that they are going to have to do it eventually but communication from Core devs have been relatively quiet this week after most miner (pools) indicated they would use Classic (if needed) to move to 2MB blocks via a HF.
I am not looking to get into yet another debate about the merits of block size, just wanted to see if you had any info I don't.(deleted image - waiting for a better miner representation)
