is it not a major concern that if its not resolved prior to the block halving, a massive surge txs before/during/after a bubble could cause serious problems?
It is all debatable. You can go back and forth with both sides with pros and cons, but in the end no one knows 100%.
The only thing that is knowable is that Segwit will not be ready before the halving and there will be no 2mb increase till after Segwit.
on a side note, do you think the resolution of the blocksize issue could be the catalyst for another price surge and possible new ath's?
I think if the issue was "resolved" (meaning a fix majority of parties are happy with) then price will definitely increase by 15%.
Will there be a surge or new ath because of it? I highly doubt it, because another fight or something else always comes along.
Next issue will be fungibility and blacklisting, I suspect.
