Is there anyway to tell what size the updates are to any given steam game?

I find myself in the same jam as I have before as my bandwidth is about $10 per gb and even though I can't find the exact size for the update to Just Cause 2...@100kbps it will take about 10 hours to download so that puts the size at about 3gb, right?.. costing me $30...meaning, I won't be playing this game again.

So for future reference, is there any way to tell what size the update that we evidently have no choice but to do (I assume so anyway) without having to aproximate the size and before I purchase the agame? I couldn't find the info anywhere.

Being forced to download outragously large updates is still rediculous. and I seriousely doubt I'm the only one who thinks so.. Origin and others don't require it, that in itself should tell you there is actually something too what I'm saying...simple logic.

It's not the end of the world for anyone and up to steam if they want to respond to the issue or not. Maybe those in the same shoes as I are such a minority steam doesn't care but it's such a needless thing to do to people/makes so little sense, unless it's somehow profitable for steam... I thought it worth the mention and always will....Hope no one minds too much. :)
