Just to put in my 2 cents worth:
I upgraded to Adobe Cloud because it was a no-brainer. They offered an introductory price of 19.99/month for existing owners of CS6 versions that did not include Premiere, After Effects and a few others.
The 19.99 got you pretty much EVERYTHING they sell, with upgrades, plus some content etc. I had been wanting After Effects for a long time, and now *BAM* for 19.99/month??? I'm IN! Have never regretted it. It's going up to 49.99/month and still worth it.
My thought is that Cakewalk does not come close to the arsenal of products under the Adobe moniker. For new customers to sign up for Platinum at 50/month, is a bit of a stretch, IMHO. I hope they've done their research (Gibson, the new owners) because I use Sonar Producer about every day for business and I'd hate to have to learn something else if they went out of business/lost market share.
I will upgrade, however. Get the discount.
Best of luck Cakewalk!
