The Next Colours in the OPI Grand Slam Collection?

I just checked OPI's twitter page and they just tweeted this picture of Serena Williams signing a tennis ball at OPI headquarters.

If you look at the bottles of nail varnish on the table can we presume that these are the colours in the rest of the collection? I spy a red and a purple for definite. A few light colours - possibly a gray? I like the look of that purple already!

Oh and I've ordered the Shattercoat and the Simply Smashing colour, so I'll review them when I get them:-)
