It's my plan too, to wait at least awhile. It is hard as a GW owner because here are all the features we are promised and have been waiting for so the temptation is strong. And we have not heard from GW for awhile, so it makes it even harder.
My hope would be that GW would at least give us some info if not the actual update before Evo3DS is released, so we can at least make an informed decision. I don't see what they gain from being quiet. Even if speculation threads are true, a dear john letter from GW would probably still have the net effect of more Evo3DS sales from people on the fence.
hey we can always sell our gateways ,probably get 60 bucks and lose 20 still worth it to sell GW and pay another 20 to upgrade to a evo after we get a positive review , hey it maybe a good time to email them and ask for a review card,
and if there is a 6.x exploit i am selling my xl too, i really hate the 2 tone color one i had to buy, maybe i will get the zelda edition next
