it might, but it's a gamble,
noone knows what effect exactly the release of ASICs will have to the bitcoin economy.
i expect the difficulty to skyrocket for several weeks/months and than almost level out until even more modern technology becomes available. but with the difficulty, the price of bitcoins may become higher.
also, even with the current difficulty it's increasingly less fun and rewarding to mine using normal computers, my computer has a pretty powerful GPU but it can hardly even make $2 per day. (it's just a gaming rig though)
I have purchased a 25GH/s BFL recently and also a 5GHs one from Ebay, i hope they both ship within reasonable timefrimes so that they at least earn their investment back.
