Ugh, the WiiU is rapidly going from a "Hmm, maybe at some point" to an absolute no buy, even without UK pricing as I write this.
1) The lure of 1080p in every title isn't happening. 720p/30 seems to be what we can expect, which is only a tiny fraction better than the PS3/360. Graphics aren't everything, but when the next generation is round the corner it counts for something. I want 1080p/30, or even 1080p/60.
2) Looks like Nintendo's typically awful approach to online services. Okay, I can post to FB/Twitter, but actual cross-game chat, friends systems and so forth? It's going to be another mess.
3) 8 or 32GB storage? Are you serious? It won't even be a proper SSD, but more akin to a big SD card in terms of speed. I have a 320GB drive in my living room PS3 and it's pretty full. I don't care that it supports external drives, I don't want to have to buy another drive and have it sitting in front of my TV. It should be integrated - even if it's a HD slot I have to populate myself (not an SD card slot either).
4) Games. I am fed up to the back teeth of Nintendo rehashing the same IP over and over and over and over. Zelda's last outing was a disappointment, entirely due to the controls and filler quests, and I have a sneaking suspicion the next will be the same. No, I don't want another Super Mario Bros game either, or another copy of Mass Effect 3 from EA.
EDIT: November 30th UK launch
