I remember similar chatter when the last flips were introduced. Bolder green border - how dare they? Adding the website address, removing the gold foil on the back etc. Change is always hard. I guess I wish they had asked the customers first - or had a poll, contest etc. Maybe even give customers the preference to use the 'old flip' for their sets etc. Maybe provide a 5 year grace period for that.
I'll wait until I see one in person before deciding. One feature I wish they (and others) would incorporate is the Q-Code (on the back). Those square bar code things. Easy to scan/verify into registries or looking up at shows.
I'll still support SGC and wish them the best.
