I’ll limit myself to the PlayStation unit of Sony and start with my biggest gripes:
Cinematic storytelling at the expense of gameplay. This is more aimed at Naughty Dog. They’re one of my favorite developers and that's why Uncharted 4 disappointed me. After having played The Last of Us that in my opinion had a perfect balance of gameplay and cutscenens, Uncharted 4 took control away too often and when it finally gave control back, the game still led you on. If God of War IV and Days Gone will take inspiration from Naughty Dog, I hope it’ll be from TLOU. I don’t want any of their future games to be as cinematic as Uncharted 4. I want them to tell more of the story through gameplay. Meaningful cutscenes are fine though. Even Wario Land had long cutscenes in the start of the game but still those games were some of my favorites on my GameBoy.
Japan Studio's lacking output. I know that Western games overtook Japanese in market share early in the 7th generation but I want Sony to strengthen their 1st party Japanese output now that they're back on track and stronger than ever. They're definitely improving with TLG, GR2 and GT Sport this year but I'm not happy before I get Ape Escape 4 and The Legend of Dragoon 2.
Too few family friendly 1st party games. I know I can’t blame Sony for the loss of Crash and Spyro (my favorite childhood PS mascots) as they never owned them in the first place and as they can’t force Activision to sell them but we need to see more of their 3D platformers return. Ratchet & Clank (2016) was great and it hopefully showed Sony that there’s still demand among PS fans.
No sustained AA and A 1st party support on Vita. I love my PS Vita and I don't think the quality of its library is that far from that of the Wii U which gets a lot of praise for its games. But still the support from Sony could’ve been far better. I completely understand why they lowered the budgets when expensive games like Uncharted: Golden Abyss and Killzone: Mercenary hardly moved any units and after smartphones and their "free" "games" invaded handheld gaming but they should've continued to develop/fund smaller AA and A games for it like Patapon, LocoRoco, Daxter, Ape Escape, Puppeteer, Knack and a port of Gran Turismo 6. Those games would've been faster and less expensive to develop and would've fitted the handheld medium a lot better than those home console look-alikes. No matter what the Vita would've probably never achieved the same success as the PSP but they could've bought a studio like Level-5 prior to Vita's launch. While not developing many AAA games Level-5 develops a bunch of great AA handheld games which is just what the Vita is missing.
Dark Cloud + Chronicle

White Knight Chronicles
Ni no Kuni
Wonder Flick
Professor Layton
Inazuma Eleven
etc.
Regarding memory cards, they should've been far more affordable but it hasn't been a huge personal issue as I bought my 64GB memory card at nippon-yasan.
Smaller:
Poor rubber on DualShock 4's thumbsticks. The DS4 is my favorite controller but I really hope they make the rubber sticks more solid on the rumored upgraded DS4 launching alongside PS4 Neo.
No displaying of total time spent playing. I'd like to see if my favorite games are also the ones receiving the most play time.
No wishlisting and gifting in PS Store. I know there's wishlisting in the browser based PS Store but why not on the PS4? And why not let customers spend money gifting each other?
No movie (both buy and rent), TV series and music in PS Store outside of US/UK. Sony creates a ton of entertainment besides games. Why not sell it themselves? More content for customers and bigger profits for Sony. Sony's own services like Crackle, PS Vue, PS Movies and PS Now need to be available worldwide asap on both PS4 and Vita.
Personally, free online multiplayer is not important as I subscribed to PS+ long before PS4 launched due to the free games but I see why it could be a big issue for Nintendo and PC gamers who consider buying a PS4.
PS3 backwards compatibility is also not that important for me as I still have my PS3 plugged in and it probably wouldn’t be complete BC anyway with support for all of my 200+ PS3 games.
