For now, the only devices that come from GPD is:
GPD-G5A+ (same as G5A, but 2GB RAM, IPS Screen and rk3288)
there are 3 other models that most probably will be announced in some time, but for now there is no info about them. (will be 5", 7" and a set top box)
when i get more info i will post.
In your opinion...
If I am looking into getting a device in the next few months should I go ahead and get the GPD-G7 or wait to see if they release a GPD-G7+
sincerelly, if you want to wait for the perfect device... you will never get one, because when you get one, manufacturers will be announcing the evolution of the same device, with improvements, etc, etc.
if you want to get one of any android device, get what you consider is suitable for you, based on the current offer.
put a list with your preferences, ordered by priority, and based on this check what you can get on the current devies that manufacturers offer.
about "plus" versions, of course will be better than their original versions, but will be more cost too. GPD-G5A is a device with a very convenient ration between specs and price, but if you consider that this device may be not enough for you, then wait for another version... or another device from another manufacturer. the good news for us, android portable gaming devices users, is that in different way than known companies than Sony or Nintendo, we have many alternatives where select what we want to buy... and will come more
