It would appear that most people can in fact expect a reduction on their royalty rate! "The royalty rate will be calculated after tax. For sales to US buyers nothing is changing: you’ll still receive 100%. For sales to buyers outside the US and EU you’ll receive up to 20% higher royalty. For sales to buyers in the EU your royalties will depend on country VAT rates. For sales to UK buyers, authors in the Bronze level will receive 1.6% less while sellers in Silver and Gold will receive 2% to 6% higher royalties." Not such an incentive afterall.
