Why so many ip6 blocks at once?
The RIPE NCC gives out /32s to ISPs, but they actually reserve a /29. This means they have to get a new /23 for every 64 ISPs that request v6 space. I imagine this gets old fast after a while. :-)

What I don't get is that they made it 16 /23s rather than one /19. (And staying on 4 bit boundaries would also seem like a slightly more obvious choice.)

but is ripe really using ip6 20 times more then rest of the world?
Not 20 times obviously... But the ARIN region does very little v6, while in Europe there are many more small ISPs than in Asia, which leads to a larger number of assignments/allocations.
