Hey TT,
I must agree with Sheba on this one, greed (read expected yearly increase in corporate profits) looks like the motivation here. Take for example the BC49 which doubled its ticket price to $1/play in tandem with CN49 this year. I have not played it since then, and don't intend to unless I can get one of my many lotto progs firing on all cylinders
BC Keno is a Casino style setup and stupid me, I did try to crunch its numbers once or twice, but with a draw every 5 min it was impossible for me to keep up that pace

.
Never paid much attention to Chaser, simply because one cannot pick the numbers, but must accept terminal generated picks. Don't think many ppl play that game cuz a quick glance at the payout shows it rarely exceeds $1000 (based on 50% of net sales). Usually you'll see it reach the 'high' around the 5-7pm slot, my take is that's when the bar crowd starts flinging their pocket change at the game

. Again, I think it's more of a Casino style type game with a draw every 1/2 hour.
I have heard of no plans for a new game in BC, but that's neither here nor there cuz I haven't been paying much attention to lotto lately, kinda busy with other stuff here for a while. So if you hear something let me know
Cheers
