Pfft, it's hardly a great thing considering this is Nintendo, who believe in charaging as much as possible for their first party games for as long as they can possibly get away with it. All their retail titles on eShop are £39.99, more than you'll see in any sane retail store I'll be damned if I ever pay that much for a 3DS game. It usually takes a year or 3 before they even considering putting their prices down too - though then again they also said they were making a concerted effort to not cannibalize retail store sales too.
it all comes down to being a smart shopper,... here (in the US) we have an electronics store (Fry's)
at which some day-1 releases (including consoles) carry a considerable price markdown
I, for example, purchased the 3ds XL on launch day for $179, marked down from the MSRP of $199
and NSMB2 for $29 (10 off from the MSRP) ... Same place where i got MK7 which was also released
for that same price
