To me it seems as if the LE-RB (Ryan Babel) has not been released in the NL at all. I bought 12 Starter Packs a few weeks ago without getting a single LE-RB.
Yesterday I went to my Panini Dealer of choice and he allowed me to open 6 Big Tin as well as 11 Small Tin Boxes. No LE-RB neither.
Not sure about your experience but this year’s release strategy by Panini is the worst ever.
Checking ebay sold listings, there's different sellers from different countries. One german has sold Babel's like crazy since April, still is. Probably this one gets the limiteds from some Panini source.
The others are from Netherlands, Belgium and even UK. These were sold in May/June, so they may be limiteds re-sold from the german seller.
So I didn't find any proof Babel is released in the Netherlands.
About release strategy from Panini... I think it's actually one of the best so far, most limiteds are not that hard to find, with the exception of Babel... even the second toughest ones, the finnish, are well known where to find.
