I really hope they find a solution that doesn't involve fractional values of Accuracy or whatever. I think the goal of making each point of an attribute matter is a good one, and if one/two of them suddenly have bonuses that only really go up every 2 points, that will be a big step back.
I don't actually think they would do it though, I'm pretty sure making each point matter was a stated goal of the system back in the day.
Fractional values, say +1.5 Accuracy, do matter. Imagine an encounter where your Accuracy equals your opponent's Deflection. A roll of 50 means you just grazed. Had you +1.5 Accuracy, it would be a hit similar to the effect of +1 or +2. In another fight, your opponent's Deflection is one higher, and you again grazed with a roll of 50. Had you +1.5 Accuracy, you would still graze (51 is the lower limit of Hits) similarly to +1, but different to +2. In the long run, +1.5 is equivalent with +1 in half of the fights, and with +2 in the other half.
Having attributes integer modifiers is only for beauty, not for game mechanics.
Edit: The above explanation is incomplete, it only shows why +1.5 is not equivalent to +2. To prove the other part, that it can differ also from +1, one assumes that enemies can have integer+half Deflection. Like -1 lower base, and +1.5 due to Resolve. In an encounter where your opponent's Deflection is higher by 0.5 than your Accuracy, you graze with a roll of 50. You would still graze with +1 Accuracy, but hit with +1.5 or with +2.
