EDIT: let me rephrase this question here
i fail to understand what the drama is all about.
the fork only needs  1 block to happen, and this one block can be delayed a little bit (a couple of minutes tops) before being mined. then the rest of the blocks building on top of it can be from nearly 0 (empty block with only coinbase tx) to 2 MB.

so where is the problem with that?

and please not that my question is not about why fork to 2 MB part, my question is about this issue and all the confused drama about it when it is pretty simple.
