500 Tender for Purchasing 11.0 Expansion - Bonus Tender for Heroic and Epic Versions

[Scumstation]

New Feats of Strength achievements on the Patch 10.1.7 PTR indicate that players will receive 500 Tender for purchasing the 11.0 expansion. Players whWarning: This has not been confirmed by Blizzard and is speculation based on datamining.

Trader's Tender for Purchasing 11.0 Expansion
In the latest Patch 10.1.7 PTR, 3 new Feats of Strength achievements were added with some very interesting names:

NEW <Hidden> Base 11.0 Tender [DNT] Reward: [DNT] 500 Tender Rewarded for Base
NEW <Hidden> Heroic 11.0 Tender [DNT] Reward: [DNT] 750 Tender Rewarded for Heroic or 250 Tender for Upgrade to Heroic
NEW <Hidden> Epic 11.0 Tender [DNT] Reward: [DNT] 1000 Tender Rewarded for Epic or 500 Tender for Upgrade from Base to Epic or 250 Tender for Upgrade from Heroic to Epic

This seems to indicate that players will receive Trader's Tender for purchasing the 11.0 expansion, whenever that is announced. WoW expansions usually come in 3 versions: Base, Heroic and Epic, with the cost and goodies increasing with each version.
WoW 11.0 Expansion Trader's Tender Amounts
From this, we can see the following amounts of Trader's Tender datamined for each version:

Base: 500 Trader's Tender
Heroic: 750 Trader's Tender
Epic: 1000 Trader's Tendero purchase the Heroic and Epic versions will receive bonus Tender.

The fact that there is now feats of strength for the next expansion makes me think that its 100% confirmed that we'll see it being revealed at Blizzcon.
