This. More hashing speed = greater security for the network. A block will still be released every 10~ minutes or so.
By all means yes, this is true. BUT! ASIC miners are MUCH faster that GPU miners, and will force GPU miners out of the game. Will GPU miners still hang around. Some of them might move to ASIC, some might not. Please do mind that Bitcoins are worthless without the community to support them. Well, this is my personal opinion, for what it is worth.
the network adjusts how hard the difficulty is, so that it works out to about 1 block every 10 minutes. So nothing changes with ASICs entering the picture except they take a greater %
but the amount stays the same.... 10(an hour) * 24(hrs in a day) * 25(coins) minted per day
