I bet it's a few 0 to add, and it's done? I read that 10mb blocks require more computational power to be processed by miners before being distributed and as such costing time which may lead to the block being orphaned or that 10 mb blocks would be to big to be move through the internet.

please let's move to the future. most pools have gb/s internet connection and super server machines. a few ns or ms more may truely be a little bit slower but if everyone has to process the 10mb block there is no edge.

and with pruning it will be as light on the disk...
