Buying A BFL 25ghs Miner

I'm thinking about buying a BFL 25GH/s miner. I also emailed them about when I should anticipate the arrival of my miner, and they said it should be somewhere around mid-july. Do you think that this technology will become obsolete by then?

While I expect the difficulty to rise once BFL releases their ASIC’s, I definitely do not believe that the technology will be obsolete by then, especially since there are very few players in the ASIC market at this time.
