Gateway plays eShop titles now, and has online, the new update will dress apps like pokebank youtube etc. I doubt theres anything on your current 3DS you wouldn't be able to get on your 4.5 one, because you'll be getting a GW for pirating purposes, look around and you'll find all the same stuff. You could also keep two, I've got one I use for legitimate reasons/online and a gateway one. My GW currently has no emuNAND and plays all titles ( or will with the new update ) so there's really no reasons not to hunt one down. I got mine on eBay for £120 brand new delivered. ... just look around, as stated it will save you money in the long run.
