While I'm terrible at predicting the future, I find this hard to believe. I think screening your DNA is something maybe upper/middle class parents might do. I do not believe it is being done by those that cannot afford it.
As the cost of doing it comes down, i would expect it to be offered more widely. I don't know if it will ever be cheap enough to offer to all prospective parents.
Oddly, the cost of doing genetic tests does not scale at all linearly:
Scanning for Downs syndrome is default in Denmark where I live. It makes a lot of sense.
You will get a probably of Downs syndrome. No one is aborting your baby - you can take an informed decision yourself.
After birth a blood test is used for scanning for 25 rare known issues.

Of course, this is exactly the point of Gattaca: you won't be "forced" to do it, but you and your child will be punished for making the socially unacceptable "choice".
The genetic tests were already down to $1,000 retail per parent a decade ago at the company I worked at and it tested for hundreds of hereditary diseases. Those base tests are even cheaper now thanks to microarrays and the mid/high end has moved up to full genome sequencing.
It won't be long before it's dirt cheap and standard in most countries, especially as the Affymetrix/Illumina patents expire and the genechips get commoditized.
In the UK, the NHS runs scans and blood tests as standard procedure at around 12 weeks, which can indicate any risk of something like Downs syndrome. You can then be referred for amniocentesis if necessary, all free at point of service. I'm sure many other European countries are similar.

(eg a single arrhythmia test is £650 - £900, but the whole panel is £1000, and then it's only another £150 to do multiple panels)
Meanwhile, sequencing a whole genome is ~$1000:

Perhaps a lot of the cost is sample preparation, and the actual molecular genetics bit is dirt cheap.
