What I'd like to see in a Pokemon game is Evolution based on regions you are in. Like for instance, the Evolution that may be happening for Farfetched... Perhaps it's never evolved in ANY of the other regions because of some strange climatic difference in those areas. Wherever this new pokemon game will be.
I must admit, the moment I couldn't return to Kanto - I lost all interest in pokemon games. Also, the cost of the handhelds you played them on became ridiculous. I'm not going to spend over 100 bucks on ONE handheld, to play ONE or two games.
Also the Eevelution debate. That doesn't look like a Normal type to me. I'd ex out a bug type, to be honest because it looks to mammalian. I'm actually going to lean towards Dragon type, simply because the way it looks leaves a very 'milotic' like view/taste in my mouth. A Dragon Eeevelution would be awesome.
I'd really like if the Pokemon games found some way to connect all the regions. I mean seriously, their is pokemon of many types in each of the different regions - and some regions share pokemon types. So obviously they are all on the same freaking planet. Someone can't tell me that there was never some idiot that decided to get on his flying pokemon and just keep flying over the water till he reached land...
