Some may, others may not. It is a choice. Some may want to go that route, but others may want the system with that amount of memory pre-installed onto it.

What happens if you own 100 games an dyou want to play one of your old games from tiem to time.  SO do we jsut delte and reisntall  and don't forget not  everyone has unlimited internet as well. Some of these gaems would eat up a person monthly data cap as well.  Remember even when you get a new hdd, you won't get teh full space as teh games you want to play will get reinstall on your new hdd eating that new space , which you bought specifically for new games. you will then end up having two copies of teh same on both hard drives.  I just don't get why they do want to implement it when both the WII u and XO have it. its for the gamers as their own slogan for the ps4.

Also if i were to order it from the US , it would take close to a month to arrive and the currency conversion will bad ot apoint i rather just but it in nz. THe price i will end up paying for it , i can a 4 tb external hdd in nz lol.

3tb HDD should have been the spaace for the launch console as 512mb is way to small. its not expensive to add a 3tb .

I thought that all your games are on disc? If yes then it takes 5 mins to delete a game and reinstall the new one 

Perhaps not, but some people may not consider buying one and are just buying the console for what is available. Keep in mind that dropping $400+ just for the console and who knows how much for games, controllers, and other add ons isn't in the cards for many.

yes but when you install a hdd into your ps4 and you want to paly an old game that was on your old hdd , thtat game will  be reinstalled onto you r new hdd and your space will be eaten up agian on the same game which already exist on your previous hdd. Howelse would have access to yoru old games if you have swapp your hdd? It takes longer then 5 mins. the installation time is not the problem here , its  having to keep on doing it , everytime you  fell like going back to one of your old games. That would be more of an inconvenance when you have tonnes of new games. They are. the only digital are the free psn plus indies. WHo wants to spend time deciding  what gaem to delete  to make up space especially fi you have a family (where time is limited) or after  a hard days work. All you want to do is put a disc and play which can do with other consoles due to external hdd support. I don't mind the idea of swappable hdd, but sony should have went with the standard size that all pc gamers use as that would have been cheaper and a logical choice.

Sounds like you should have waited to upgrade to next gen. It's just not for you.

If they went with the standard size which pc builders use , then having that big size wouldn't have increased the price by that much. it would alot cheaper then havign the one taht sony used in their ps4. If not that , then at least have the option to have external hdd support or if they wanted to go  with the swappable hdd, then at least use the standard size which pc builders use , so that down the track , gamers cna easily replaced them and replace them cheaply with a much much bigger size. As i mentioned , i can get 3 tb hdd the one pc builders use ofr the smae price of the 1tb hdd that sony ps4 uses. Either of these options would have been good for the gamers.

Lol if i had to wait for sony to do that ,  i would be  waiting till the end of this generation before they implement. i can bet  that they will never do it . Plus i am also a collector, i like to own all consoles , especially on launch day. i already begun buying mint condition consoles back in the 80s and even earlier than that .  I jsut got a gmaing pc so any multiplat where pc has a huge advantage when it comes to third party games, i will jsut buy it on my pc . I am fine with XO nad WII u. both are excellent machines. I laready have a 3 t external hdd for the XO and i hav already used more then 20% of it , not counting the default 512gb that came with it. 

I'm thinking the totally opposite thing - PS4 is much better than Xbone. You want more space on PS4? Change the internal HDD! I hate the fact that MS made it impossible for me to swap the internal HDD. Xbone owners are stuck with that ridiculous HDD, while PS4 gamers can upgrade without thrashing the living room, they could even speed up the console with SSD/hybrid SSHD. The options are there for PS4, but not for Xbone and I just don't want any more boxes next to my TV!

BTW. And what happens when the HDD in Xbone dies?
