Very excited for this. Everything I've seen so far is what I had hoped for (and thanks to Eurogamer/WSJ, expected). Don't care too much about power so it being primarily a handheld doesn't concern me at all. I prefer to play games with the console in my hands, but not necessarily outside of my home and this is by far the best implementation of this idea on the market. Additionally many Nintendo games (especially Pokemon) are among my favourites so I know I'll get enough games to play even if third parties drop it again, especially now that the whole of Nintendo is working on one system and there are rumblings about Nintendo trying to make development much more efficient. Given Eurogamer was right about basically everything, I'm expecting it to be region-free but I'm awaiting an official announcement. 3DS/Wii U being region locked was by far the worst thing about them for me.
Only real concern is the price, hope that gets announced soon. If I can find it for £250 I'll get it day one, otherwise I'll wait until I can. Oh, and I do hope Virtual console purchases will be fully transferable without paying an upgrade fee. If not, I simply won't be using the VC again.
