The VSTs from your previous purchase will work.
 
Here is a chart of the differences between the tiers

So no Vocal align, nor Drum Replacer when that becomes available. The former you can do with Melodyne or Audio snap, and the latter is really only important if you have live drums or loops. You'll get ARA so your previous melodyne should work. You'll still have Pro Channal, just not expandable.
 
If you can put up with that for a year, then you'll probably move up a tier with out a surcharge, and I'm imagining they'll will have some different bundled stuff. If there is a surcharge, then upgrade in 14 months to Platinum and the surcharge will probably be negated.

Yeah, someone else already suggested me the JRR deal. Also given that via the Cakewalk shop everything is in Euro for me, the difference becomes even more substantial: Platinum would then cost me €144 instead of €199. So yeah, I am actually still contemplating going for Platinum after all, even though it's still a fair bit above the €49 or €99 Artist options from my opening post.
