It hit 280 on cryptsy yesterday, so I wouldn't be surprised to see it do that today as well, or even surpass it. Max on BTER was 298, so going past the magic 300 limit is a possibility. Looking at the walls, there's 60 BTC at 275, 42 at 280, 33 at 282, 30 at 289, 65 at 290, 60 at 296, 79 at 299 and 89 at 300. A couple of walls at 303, 306 and 307 as well.. after that it's fairly quiet until you get closer to 400.
