No, I wouldn't say so. They have the play off semis to promote and 70 odd thousand tickets to shift for the Grand final. All focus and energy needs to be concentrated on that at the moment. The promotion for the Wembley double-header should begin at the Grand Final with a press release about the extended seating sent out on the Monday afterwards.
If they were to open the upper tier with lower priced tickets now that would detract some attention away from the Grand Final and means that folk are more likely to buy the cheap tickets behind the sticks than the more expensive ones in the middle of the pitch. This way they're concentrating resources and making sure there is less chance of big gaps in the middle of the pitch.
I'd say the best course of action would be to open up the upper tier of Wembley, have a knock down price range (£10-25 adults, £10 all concessions) and launch it at the Grand Final by getting the England train on squad, all wearing England jackets, to walk on pitch before the match and have someone announce the new offer.
