As far as new customers getting "new max" vs. "old max", I think the difference is how many boxes they are ordering. It appears when SaskTel is giving people multiple modems to satisfy the bandwidth requirements, you're getting old max. This happened to me at the end of September. I called in and dropped my order to just fit onto the bandwidth requirement of 1 modem, and so I convinced them to send an installer out with new max boxes, cuz that's what I ordered. I now have new max, all going through 1 modem, and media room is fantastic.

Just a reminder: If you have multiple modems to satisfy bandwidth requirements, the multi-room feature WILL NOT WORK. Get your services evaluated to fit onto 1 modem if you want multi-room to work. (Unless... maybe SaskTel will find a way to bridge two modems together to allow the boxes to network together on two modems... but I highly doubt that)
