So I guess if you want to at least get 1-2% back while you can, now is the time to spend your points.
I'm wondering if going on a binge before the month ends would be worth it. I definitely want to spend all my MSP balance before the conversion, and that won't be a problem since I have a lot Rock Band dlc I want. I kind of doubt the conversion FAQ saying converted funds won't be taxed when used to make a purchase will hold up as true. What's holding me back is maybe when Xbox Live Rewards relaunches it will have that dlc punchcard we have all been waiting for.
I already spent 800 MSP this month. I think I'll just buy The Doors and David Bowie Rock Band 3 track packs. That'll put me at 3080 MSP for the month, so I'll get 70 MSP back. Eh, I'll spend an extra 440 MSP to get 80 MSP back; that'd be a free legacy Rock Band track. That is, if I have no interest in the next three DotW. I'll just look to spend 3520 MSP or a bit more this month.
I just hope we get a couple days notice before the new dashboard goes live for everyone. I'm guessing the Xbox Live Rewards relaunch will have the new dashboard in mind. If Xbox Live Rewards has a cashback reward then I think the new dashboard will go live sometime around the relaunch, September 1.
