Sounds like there will be SOME cheaper seats in limited locations around the ground, whilst at the same time most prices are going up. Affordable for some, more costly for most == more total revenue if the ground is sold out. Prices based on who they are playing, other clubs also do this, so if you need to see a Chiefs game, just any game, you will be able to buy a cheap ticket for at least one game over the season, but if you want to see every game, expect to pay more in total.
Very woolly wordy way to say we have increased average prices, but some better prices are to be had.
