I did see a few INAs in Newfoundland as early as December, and they were all in the 4 million range. Yep, I think it's safe to say that printer letter I has finally arrived to my province.
Considering that Newfoundland usually doesn't start getting new $5 and $20 bills until the spring (given their high demand) - possibly due to weather causing potential ferry delays and prompting the banks to order at least a three-month supply of money prior to Christmas - I suspect that INC or a new prefix in the new signature combo will appear in my province as early as April. I strongly doubt banks in my region will receive orders of new INB and INDs, as they've been released in Canada many months ago. Newfoundland seems to usually see new prefixes that are not as abundant in Canada. I remember when the $5 Frontiers HCG first got reported on the forums, and there was a dry spell for such prefix for months or even over a year on end, and I suspected that prefix would be likely to arrive in Newfoundland. It did.
