WestJet did not renew with Mosaik. I haven't figured out exactly how that affects the number of airmiles I will need to get tickets to Orlando for next February but I almost had enough (2800 air miles) for two tickets on WestJet.
You still have enough for 2 r/t tic to Orlando in Feb 2009 if you book right now!
I called Airmiles today to see what is happening about the WestJet Mosaic Masercard deal
I was told that the Westjet offer that allows cardholders to buy a roundtrip airfare for 1400 in off season or 1600 in high season will end as of July 31st, 2008 :

But, that being said, you can still book using the airmiles you have and they are taking bookings up to mid Feb 2009 right now.
The rep told me that flights can be booked 300 days in advance, so if you want to use your current airmiles under this plan, you will have to do it before July 31st to get the best value for use of airmiles.
After July 31st, they will offer 20% discount off of regular amount of airmiles required.
I have 3200 airmiles right now and am looking over my calendar to see where & when I can use them to take advantage of the better offer.
Once July 31st is here, the value of the airmiles is depreciated
Hope this helps
