It's not too far-fetched an idea that Sony or Microsoft could release a SKU of the PS4/Xbox One that does not have a disc drive. This would fit in well with the digital future they would no doubt like to see for game purchases.

It's possible that doing that could drop the price of the consoles anywhere from $50-$100.

If you knew this was coming which console version would you prefer? With a disc drive or without?

Ps4 go?

Drive less version would only be practical if you have a very fast internet provider without any data limits. For the majority of users it would be very impractical. Since most people have not so fast internet with data caps.

It would need to be cheaper and have a 1T HD for it to be worth it.

I'd want that but it isn't going to happen. sony/microsoft need shelf space at stores

I don't think bandwidth limits are very commong outside the US. At least they're extremely rare in Finland. Also, fast internet connections are becoming more and more common.

tell that to valve

Well most providers in the US have data caps unless you are very lucky and have Google fiber which is ultra fast and has no data caps.

A BD-ROM drive costs less than $20... You won't see a big impact on price.

I don't know how it is in the rest of the U.S or the rest of the world, but both Verizon and Comcast (the two largest internet providers in the areas I've lived in) have unlimited data for all of their home internet services, including the cheapest plans. The average download speed in the U.S is 7.4 Mbps. Considering the people who would want a console like this would be in the upper rather than lower 50%, we can expect 2-4 hours for a file that is 10 GB - 20GB (with compression this is possible for blu-ray games.) That is less than a day at work/school/etc. Certainly there is a market for these type of people.
