@anonymoustroll420: strictly speaking it is not a blocksize increase. Stuff has been moved in another place to make room for other transactions.
As far as I know blocksize is the same and that's the reason for "2x or not 2x". But this is another story.
No, that is strictly false. Segwit is a block size increase; the size of a block message can be up to 4 MB now. 2x is yet another block size increase; it makes the maximum 8 MB.
