Those cheeky fellows working in Blizzard have plonked an ad for Mists of Pandaria in the character screen you see after login.
It is not subtle or unreasonable, and after my initial reaction of “what the f?” I considered using that to purchase my upgrade.
It makes me ponder if we will see character customisation, race change, name change and such in that screen too. Heck it would even be handy to be able to buy month-by-month time as well. The user is logged in, so might benefit from it. All the special offers for pets and such could be there too.
Are you pondering that already Activision?
