This was maybe the most boring E3 I can remember, almost no noteworthy news.
AMDs new CPUs, the Ryzen 3000 line, look pretty great. I'm planning to build a new PC with one of those now, once the dust settles and they're readily available, maybe this Fall or a bit later.
AMDs GPUs on the other hand... still pretty ho-hum. They can't compete with nVidia on the high end. I'll keep my 1080 GTX and use that in the new system for now. The 2080Ti RTX cards are like $1100. No chance in hell. $500 is the most I'd even consider for a video card, and $300-400 is far more likely. I'd also like one with a ton of VRAM, like 16GB, and nothing much like that which is also better than my 1080 is even on the horizon.
Microsoft announced the next XBOX, but didn't give it an official name yet. They'll probably make it even more confusing in the end and just call it "XBOX" or something.
Microsoft: "It's going to be more powerful than the current one!"
Everyone: "No shit. There would literally be no point in putting out a new box if it wasn't."
It's supposed to play all the XBox One games, I think, and they SEEM to be saying it'll play the X360 and original XBOX games that are already backwards-compatible on the current XBox One. That's a fair number of X360 games but only a few original XBox games - I haven't seen Burnout 3 on the list for instance, and that one IS playable on the X360. Doesn't make a lot of sense considering how the original XBOX was basically a PC, the XBONE is a PC, and the XBOX4 will also be a PC... The X360 is the oddball one (PowerPC CPU) that might be hard to emulate, not the original XBOX.
Halo 6 will be a launch title for the next XBOX too. Good move to promote it, but it also means they're throwing in the towel on the XBox One, they're clearly resigned to losing this generation and they're done with it. No gameplay footage or anything either so...
Sony did most of their announcements well before E3 and basically the same as Microsoft's announcement; the PS5 will be more powerful than the PS4, it'll play all, or at least most PS4 games, and they haven't definitively said this, but it probably won't play PS1/PS2/PS3 games - at least not from disc. I suspect you'll be able to buy some of them digitally, but they still won't play from disc. I really want a PS5 that plays EVERY PlayStation game and an XBOX4 that plays EVERY XBOX game. Doesn't look likely though.
The PS5 hardware sounds slightly more interesting than the XBOX4, because it's supposed to have an integrated SSD that speeds up load times by a huge amount, and they're using some sort of very-fast VRAM in it too (similar to what they did in the PS4).
Seems like the next PlayStation & XBox are both coming late 2020. Again, no real surprise there.
Nintendo probably had the best showing just by announcing sequels that you'd generally expect from Nintendo. The most interesting thing was the direct sequel to Zelda: Breath of the Wild. I don't think Nintendo has ever done that with a Zelda game before. They probably want to get more mileage out of that game engine. They did do a similar thing with Mario Galaxy 1 & 2 though.
