Not really. I've not really found anything enticing on other platforms. There's a couple of "oh, that'd be nice if I had the console", but nothing I feel like I'm missing out on. Haven't touched my 360 since GTAV and my PS3 is just a BluRay/Netflix/4oD machine now.
The Nintendo platforms provide what I need. I don't care about military shooters, hyper realistic graphics or games that rely too much on narrative and less on actual gameplay, so there's little out on the other platforms that are enticing to me at this point.
I also don't like the seeming lack of quality control that exists on the other platforms. Too often games are put out, and there have to be huge patches either day one or soon after (or in Halo's case, 6 months after) just to fix it and bring it up to be a quality product. Nintendo's games are mostly without this, seldom even having a patch and often when it does get a patch, it's typically to add new functionality rather than just to fix things.
What will change that? Red Dead Redemption sequel. Maybe Assassin's Creed Victory (I've wanted Victorian London for ages). Mass Effect that takes it back to basics and a few others.
Nintendo's games really, they bring out a joy in me others don't. While playing through various games, I feel "Yeah this is a decent enough game. Well made, long, compelling etc.", but while playing Nintendo made games, I just end up with a big grin on my face. When I die in a stage, rather than utter profanity, I just burst into laughter. That's what gaming is to me, and that's why being Nintendo only so far this generation hasn't ruined gaming for me. If anything, it saved it after the mundane feelings I was having towards the end of last generation.
