What makes people think PS3 can reach 100m sales ?

I doubt it will sell 5m this year which would be great BTW.

No, they wouldn't piss off their consumers like that. They said the PS3 would have 10 years of life, and now they've said that PS4 will have the same. If they kill off the PS3 now, a lot of pissed off PS3 players, who doesn't want to invest in a PS4 just yet, wouldn't trust Sony to support the PS4. Then the consumers who doesn't want a PS4 just yet won't buy it later because it won't be supported then, by looking back at what they did with the previous platform (PS3).

Also not nearly the install base of the PS3 will move to the PS4, so there would be lots of lost profit.

Every new PS console launch spans these specious arguments on how they need to ditch the old and rush head long into the new ignoring the fact that the old console at this point is almost all profit and therefore would be a very bad business move for Sony.

It aint the WiiU , the Dreamcast or the original XBOX. The PS3 has 80 or so million current owners who are still invested in their console and when compared to the PS4 game for game the PS3 will sell more copies just based on the install base being 20x times that of the PS4. Not to mention all of those PS3 owners are possible future PS4 owners and just dropping support would alienate them big time especially since the PS4 has no B/C and it's just not feasible to just add B/C to the PS4.

Also, PS3 is NOT restricting sales of the PS4. Lack of availability is.

Only because for some strange reason, you predict only 4M for 2014. Games still coming, price drop, being released in emerging markets, etc. are all still possible this year.

wut

Wich part of "Sony" didnt you understand? Yeah they got some DLC and the yearly baseball game no one cares about. I consider that nothing.

The good games are coming from third parties.

Uhhh no... The ps3 will be pumping out jrpgs in the years to come.

I disagree.

There are several "good" reasons why Sony should NOT discontinue the PS3.

1. Profit. PS3 makes a profit for them. Why would they want to kill off a source of profit?

2. Sony have always prided themselves on supporting their previous consoles (last gen). If they killed off the PS3 so soon then they would be no different to Microsoft (no offence intended).

3. Cheaper console for those who can't afford PS4. Yes. Not all of us are loaded with money. Those who can't afford PS4 (for whatever reason) can buy a PS3 and enjoy it's games (new and old).

P.S. I expect the PS3 to scrape over the 100 million sales milestone. It'll be an INCREDIBLE feat if it achieves it. Once laughed at as a failure. It is now getting closer to emulating the remarkable sales of the PS1. Only time will tell though.

One of the reason i want the PS4 is the extreme longevity of sony's console (support wise). If ps3 died now, I would be hugely disappointed. I may still buy a ps4 tough.

Wow really 4.5m only? What about the 360 then? 2m this year and death in early 2015? I don't hope so for either of them.
