They say u can play while downloading (negating the argument that "good luck downloading 60gb" argument). What if the PS4 has no drive, huge terabyte HDD, all just digital distribution?

While a good idea, i think alot of countries do not have good internet connection; not sure if that's a good idea.

I agreed, also now they have develop this play as you download algorithm, i think if not PS4, then PS5 will definitely be just dL only

Too many rumors for you.
YEah I saw the same twitter that said "No disc drive"

It was a forgery. Rest your pretty little head.
(If anything it might be an alternative SKU)

OP has a point. We'll see at E3.

After PSP go Sony would not be crazy to pull the digital-only stunt again in a handheld, let alone in a home console.

It will have a disc drive.
