According to some people Nintendo skips every year

Well think about it like this, if Sony aren't there at all, then every AAA 3rd party game is actually going to look like an X1 exclusive, I'd wager that a drinking game for the MS show which involved even drinking a sip of water each time the word Exclusive is uttered would have you drowned at your PC.

Like I said in my article comment on this, before the holiday season is a very poor time to even hint that you're changing the playing field... when you are dominating the game as it stands, it would be like a team going 10:0 up and then announcing plans to sub out their Goalie.... for something different... like a can of Pepsi max in a dressing gown. Sony have said a few times this Generation that they were even shocked at the success the PS4 had... if they have stumbled onto a winning formula they shouldn't do a damn thing that could upset that, especially given they're not certain what caused it as they might not be able to repeat that again with the PS5, there was a lot of factors involved in making the PS4 the dominant selling beast what it is right now, and honestly Sony can't control or replicate those again, unless Sony force MS to rehire Don Mattick and send him out on stage to reveal another new system and then suggest that if people don't like it they can stick to playing the X360 again.

Also ... consider those people who've not bought a PS4 by now, surely they have to be the most casual / thrifty of gamer that after 5 years on the market now is the time they think to jump in, it's people like that in my opinion that could well tighten their purse strings yet again when the news of Sony stopping a 24 year tradition of going to E3 hits.

Man and I was hoping for FF7Remake to appear at E3 LOL

That’s nonsense. Microsoft always try to make all the multiplatform games they show look as if they were exclusives. Gamers aren’t stupid. It’s not gonna make a difference. Microsoft better hope Sony won’t tease PS5 before E3, like that Resetera rumour suggests.

There are still going to be game announcements and lots of new trailers anyway.

They don't have anything to prove in terms of PS4 anymore, but pushing in the clutch is one thing, never shifting into another gear, even one or two lower, for miles, is another. I think they'll drop PS4 to $249 early 2019, maybe bundled, and then officially announce $199 just before, or sometime during the PS5 reveal.

As long as they reveal before the year is over. Even though Feb 2020 would only be a couple months away, if they waited to reveal until then, assuming a holiday launch, I think an entire year gap in between 2018 and 2019 without a flood of heavy hitting games would lead to a breakdown in brand loyalty and hype for some. It also leaves the door wide open for MS and Nin, and they would be fools not to try and take major advantage of it in whatever way they can. With an early 2020 launch, PS needs to make sure they announce the price with enough notice before xmas, so interested gamers can then leave the tree a little bare and march right into PS5 at launch.

Can you elaborate?

OT:

Kinda sad though. E3 is always a yearly event for me watching and expecting new announcement especially for my preferred console. 

There’s two side of the coin in here.

1st one is very scary for it’s competitor, silence is deafining. While the other one is screaming like crazy and showcasing their ammos. While Sony is very silent preparing to counter attack with their special ammo.

2nd one is they really don’t have anything to showcase anymore for PS4 and all the bullets have been used so they don’t have anything to showcase anymore and they are prepping up for 2020. The last few game/s announcments are VGA and the fan meeting of Japan studio.

My sentiments here lies that Sony really made a bad move in closing their studios.

Zipper, evolution, GG cambridge, liver pool. Instead of closing them they should have stick with it and asked them to create new ip that they want to make. Letting go of Ready at Dawn when order game didn’t fly th charts.

Not giving Japan studios the proper funds to make games. PS4 this late is the perfect time to realease more new ips. PS4 install base is large and with how big social media are then it can generate hype.

In all honesty, you say gamers aren't stupid, there is a reason why exclusive was uttered so many times this last E3 by MS even though not a single game shown was actually exclusive to their platform, each game had some caveat such as exclusive for the home consoles, exclusive with certain skins.... or exclusive until someone turns to the left in the shop and sees the game on the PS4. MS's marketing team targets the stupid gamer who walks away thinking that the system does actually have a series of games which are only available on the X1, they spend millions on marketing the system as such and targeting those "stupid" gamers.

But aye, you put on an E3 show with MS and Nintendo as the only two systems there, it's gonna seem like you have 2 different options for games and all those things like Madden, WWE, Call of duty, Battlefield, Star Wars all those games... they're only gonna be on one stage and will all likely have a giant EXCLUSIVE sign on the trailer in 10 foot tall lettering alongside the finest of fine print which states that the game is coming with an exclusive green lootbox you can buy after launch.

Copy Nintendo way is a strong point of Sony after all

If I'm not mistaken, none of the multiplat games MS showed in their conference appeared on Sony presentation, and I don't think that many people thought they were exclusive to xbox. At the end of the day, Sony can still post the trailers on YouTube, show them in PS4 ads on TV and make marketing deals, which they'll most certainly do. 

PlayStation kicking ass so bad they can take a year off and prolly still kick ass 😂😂😂😂

wow, what a generation it has been for them.
