Why am I not excited about this?
Well I see this new "console" to be exactly like every other Nintendo release, it'll never play the AAA titles in all their graphical glory, it wont push the boundries of technology and inspire companies to develop for it instead of the Mainstream consoles like Playstation and XBOX. This Nintendo Switch is basically just a £280 novelty item... Sure I might like the idea of playing Pokemon on it, or maybe a few other titles, so yea about 3 games maybe I would play on it. Is it worth it? If you don't have another hand held console... Yes it's worth it but I'm sure it will be sidelined next to your PC/Consoles in no time and the novelty of this will wear off quickly.
I did mention that there wont be many AAA titles, there will be a few upon launch, because why would a developer not jump on a new console release band wagon? It's basically free promotion, but when the game sales start dropping so will the time into developing these games! The games I expect to see on this console will be little kids games, cartoon style animation which requires not a lot of graphical power.
So already before it's release, I'm somewhat disappointed, but this is the route that Nintendo has choosen for itself, it will never get out of this 4th place runner up as far as gaming goes (Next to PC, Playstation and XBOX)
