If we really want bitcoin a means of payment for masses (like Roger states), we would need thousands of transaction per second. So increasing block size is NEVER a real solution.
well it might be, you just don't know how tech is going to be....and what will be cored in, plus what usually happens is BU if it won out would have to adopt a segwit soln down the track anyway
That means BU would start with slightly increased block size (let's say doubled) to ease the urgent problems and then do almost the same as the core devs, but with the power in BU's hands?
